Commit d6e0b7fa1186 ("slub: make dead caches discard free slabs
immediately") makes put_cpu_partial() run with preemption disabled and
interrupts disabled when calling unfreeze_partials().
The comment: "put_cpu_partial() is done without interrupts disabled and
without preemption disabled" looks obsolete, so remove it.

Start address calculated for slab padding restoration was wrong. Wrong

slab_state is being set to "UP" in create_kmalloc_caches(), and later on
we set it again in kmem_cache_init_late(), but slab_state does not
change in the meantime.
Remove the redundant assignment from kmem_cache_init_late().
And unless I overlooked anything, the same goes for "slab_state = FULL".
slab_state is set to "FULL" in kmem_cache_init_late(), but it is later
being set again in cpucache_init(), which gets called from
do_initcall_level(). So remove the assignment from cpucache_init() as
well.

We should not reuse the dirty bh in jbd2 directly due to the following
situation:
1. When removing extent rec, we will dirty the bhs of extent rec and
truncate log at the same time, and hand them over to jbd2.
2. The bhs are submitted to jbd2 area successfully.
3. The write-back thread of device help flush the bhs to disk but
encounter write error due to abnormal storage link.
4. After a while the storage link become normal. Truncate log flush
worker triggered by the next space reclaiming found the dirty bh of
truncate log and clear its 'BH_Write_EIO' and then set it uptodate in
__ocfs2_journal_access():
ocfs2_truncate_log_worker
ocfs2_flush_truncate_log
__ocfs2_flush_truncate_log
ocfs2_replay_truncate_records
ocfs2_journal_access_di
__ocfs2_journal_access // here we clear io_error and set 'tl_bh' uptodata.
5. Then jbd2 will flush the bh of truncate log to disk, but the bh of
extent rec is still in error state, and unfortunately nobody will
take care of it.
6. At last the space of extent rec was not reduced, but truncate log
flush worker have given it back to globalalloc. That will cause
duplicate cluster problem which could be identified by fsck.ocfs2.
Sadly we can hardly revert this but set fs read-only in case of ruining
atomicity and consistency of space reclaim.

Patch series "ocfs2: add nowait aio support", v4.
VFS layer has introduced the non-blocking aio flag IOCB_NOWAIT, which
tells the kernel to bail out if an AIO request will block for reasons
such as file allocations, or writeback triggering, or would block while
allocating requests while performing direct I/O.
Subsequently, pwritev2/preadv2 also can leverage this part of kernel
code. So far, ext4/xfs/btrfs have supported this feature. Add the
related code for the ocfs2 file system.
This patch (of 3):
Add ocfs2_try_rw_lock and ocfs2_try_inode_lock functions, which will be
used in non-blocking IO scenarios.

ocfs2 supports trimming the underlying disk via the fstrim command. But
there is a problem, ocfs2 is a shared disk cluster file system, if the
user configures a scheduled fstrim job on each file system node, this
will trigger multiple nodes trimming a shared disk simultaneously, which
is very wasteful for CPU and IO consumption. This also might negatively
affect the lifetime of poor-quality SSD devices.
So we introduce a trimfs dlm lock to communicate with each other in this
case, which will make only one fstrim command to do the trimming on a
shared disk among the cluster. The fstrim commands from the other nodes
should wait for the first fstrim to finish and return success directly,
to avoid running the same trim on the shared disk again.

The BUG code told that extent tree wants to grow but no metadata was
reserved ahead of time. From my investigation into this issue, the root
cause it that although enough metadata is not reserved, there should be
enough for following use. Rightmost extent is merged into its left one
due to a certain times of marking extent written. Because during
marking extent written, we got many physically continuous extents. At
last, an empty extent showed up and the rightmost path is removed from
extent tree.
Add a new mechanism to reuse extent block cached in dealloc which were
just unlinked from extent tree to solve this crash issue.
Criteria is that during marking extents *written*, if extent rotation
and merging results in unlinking extent with growing extent tree later
without any metadata reserved ahead of time, try to reuse those extents
in dealloc in which deleted extents are cached.
Also, this patch addresses the issue John reported that ::dw_zero_count
is not calculated properly.
After applying this patch, the issue John reported was gone. Thanks for
the reproducer provided by John. And this patch has passed
ocfs2-test(29 cases) suite running by New H3C Group.

The race between *set_acl and *get_acl will cause getting incomplete
xattr data as below:
processA processB
ocfs2_set_acl
ocfs2_xattr_set
__ocfs2_xattr_set_handle
ocfs2_get_acl_nolock
ocfs2_xattr_get_nolock:
processB may get incomplete xattr data if processA hasn't set_acl done.
So we should use 'ip_xattr_sem' to protect getting extended attribute in
ocfs2_get_acl_nolock(), as other processes could be changing it
concurrently.

If we can't get inode lock immediately in the function
ocfs2_inode_lock_with_page() when reading a page, we should not return
directly here, since this will lead to a softlockup problem when the
kernel is configured with CONFIG_PREEMPT is not set. The method is to
get a blocking lock and immediately unlock before returning, this can
avoid CPU resource waste due to lots of retries, and benefits fairness
in getting lock among multiple nodes, increase efficiency in case
modifying the same file frequently from multiple nodes.
The softlockup crash (when set /proc/sys/kernel/softlockup_panic to 1)

If metadata is corrupted such as 'invalid inode block', we will get
failed by calling 'mount()' and then set filesystem readonly as below:
ocfs2_mount
ocfs2_initialize_super
ocfs2_init_global_system_inodes
ocfs2_iget
ocfs2_read_locked_inode
ocfs2_validate_inode_block
ocfs2_error
ocfs2_handle_error
ocfs2_set_ro_flag(osb, 0); // set readonly
In this situation we need return -EROFS to 'mount.ocfs2', so that user
can fix it by fsck. And then mount again. In addition, 'mount.ocfs2'
should be updated correspondingly as it only return 1 for all errno.
And I will post a patch for 'mount.ocfs2' too.

When some nodes of cluster face with TCP connection fault, ocfs2 will
pick up a quorum to continue to work and other nodes will be fenced by
resetting host.
In order to decide which node should be fenced, ocfs2 leverages
o2quo_state::qs_holds. If that variable is reduced to zero, then a try
to decide if fence local node is performed. However, under a specific
scenario that local node is not disconnected from others at the same
time, above method has a problem to reduce ::qs_holds to zero.
Because, o2net 90s idle timer corresponding to different nodes is
triggered one after another.
node 2 node 3
90s idle timer elapses
clear ::qs_conn_bm
set hold
40s is passed
90 idle timer elapses
clear ::qs_conn_bm
set hold
still up timer elapses
clear hold (NOT to zero )
90s idle timer elapses AGAIN
still up timer elapses.
clear hold
still up timer elapses
To solve this issue, a node which has already be evicted from
::qs_conn_bm can't set hold again and again invoked from idle timer.

Add an obvious error message, due to mismatched cluster names between
on-disk and in the current cluster. We can meet this case during OCFS2
cluster migration.
If we can give the user an obvious tip for why they can not mount the
file system after migration, they can quickly fix this mismatch problem.
Second, also move printing ocfs2_fill_super() errno to the front of
ocfs2_dismount_volume(), since ocfs2_dismount_volume() will also print
its own message.
I looked through all the code of OCFS2 (include o2cb); there is not any
place which returns this error. In fact, the function calling path
ocfs2_fill_super -> ocfs2_mount_volume -> ocfs2_dlm_init ->
dlm_new_lockspace is a very specific one. We can use this errno to give
the user a more clear tip, since this case is a little common during
cluster migration, but the customer can quickly get the failure cause if
there is a error printed. Also, I think it is not possible to add this
errno in the o2cb path during ocfs2_dlm_init(), since the o2cb code has
been stable for a long time.
We only print this error tip when the user uses pcmk stack, since using
the o2cb stack the user will not meet this error.

In case of running scripts/decodecode without any parameters in order to
give a copy'n'pasted Code line from, for example, email it would parse
only first line of it, while in emails it's split to few.
ie, when you have a file out of oops the Code line looks like
Code: hh hh ... <hh> ... hh\n
When copy'n'paste from, for example, email where sender or some middle
MTA split it, the line looks like:
Code: hh hh ... hh\n
hh ... <hh> ... hh\n
hh hh ... hh\n
The Code line followed by another oops line usually contains characters
out of hex digit + space + < + > set.
So add logic to join this split back if and only if the following lines
have hex digits, or spaces, or '<', or '>' characters. It will be quite
unlikely to have a broken input in well formed Oops or dmesg, thus a
simple regex is being used.

Pull integrity updates from James Morris:
"This contains a mixture of bug fixes, code cleanup, and new
functionality. Of note is the integrity cache locking fix, file change
detection, and support for a new EVM portable and immutable signature
type.
The re-introduction of the integrity cache lock (iint) fixes the
problem of attempting to take the i_rwsem shared a second time, when
it was previously taken exclusively. Defining atomic flags resolves
the original iint/i_rwsem circular locking - accessing the file data
vs. modifying the file metadata. Although it fixes the O_DIRECT
problem as well, a subsequent patch is needed to remove the explicit
O_DIRECT prevention.
For performance reasons, detecting when a file has changed and needs
to be re-measured, re-appraised, and/or re-audited, was limited to
after the last writer has closed, and only if the file data has
changed. Detecting file change is based on i_version. For filesystems
that do not support i_version, remote filesystems, or userspace
filesystems, the file was measured, appraised and/or audited once and
never re-evaluated. Now local filesystems, which do not support
i_version or are not mounted with the i_version option, assume the
file has changed and are required to re-evaluate the file. This change
does not address detecting file change on remote or userspace
filesystems.
Unlike file data signatures, which can be included and distributed in
software packages (eg. rpm, deb), the existing EVM signature, which
protects the file metadata, could not be included in software
packages, as it includes file system specific information (eg. i_ino,
possibly the UUID). This pull request defines a new EVM portable and
immutable file metadata signature format, which can be included in
software packages"

Pull GPIO updates from Linus Walleij:
"The is the bulk of GPIO changes for the v4.16 kernel cycle. It is
pretty calm this time around I think. I even got time to get to things
like starting to clean up header includes.
Core changes:
- Disallow open drain and open source flags to be set simultaneously.
This doesn't make electrical sense, and would the hardware actually
respond to this setting, the result would be short circuit.
- ACPI GPIO has a new core infrastructure for handling quirks. The
quirks are there to deal with broken ACPI tables centrally instead
of pushing the work to individual drivers. In the world of BIOS
writers, the ACPI tables are perfect. Until they find a mistake in
it. When such a mistake is found, we can patch it with a quirk. It
should never happen, the problem is that it happens. So we
accomodate for it.
- Several documentation updates.
- Revert the patch setting up initial direction state from reading
the device. This was causing bad things for drivers that can't read
status on all its pins. It is only affecting debugfs information
quality.
- Label descriptors with the device name if no explicit label is
passed in.
- Pave the ground for transitioning SPI and regulators to use GPIO
descriptors by implementing some quirks in the device tree GPIO
parsing code.
New drivers:
- New driver for the Access PCIe IDIO 24 family.
Other:
- Major refactorings and improvements to the GPIO mockup driver used
for test and verification.
- Moved the AXP209 driver over to pin control since it gained a pin
control back-end. These patches will appear (with the same hashes)
in the pin control pull request as well.
- Convert the onewire GPIO driver w1-gpio to use descriptors. This is
merged here since the W1 maintainers send very few pull requests
and he ACKed it.
- Start to clean up driver headers using <linux/gpio.h> to just use
<linux/gpio/driver.h> as appropriate"

Pull device mapper updates from Mike Snitzer:
- DM core fixes to ensure that bio submission follows a depth-first
tree walk; this is critical to allow forward progress without the
need to use the bioset's BIOSET_NEED_RESCUER.
- Remove DM core's BIOSET_NEED_RESCUER based dm_offload infrastructure.
- DM core cleanups and improvements to make bio-based DM more efficient
(e.g. reduced memory footprint as well leveraging per-bio-data more).
- Introduce new bio-based mode (DM_TYPE_NVME_BIO_BASED) that leverages
the more direct IO submission path in the block layer; this mode is
used by DM multipath and also optimizes targets like DM thin-pool
that stack directly on NVMe data device.
- DM multipath improvements to factor out legacy SCSI-only (e.g.
scsi_dh) code paths to allow for more optimized support for NVMe
multipath.
- A fix for DM multipath path selectors (service-time and queue-length)
to select paths in a more balanced way; largely academic but doesn't
hurt.
- Numerous DM raid target fixes and improvements.
- Add a new DM "unstriped" target that enables Intel to workaround
firmware limitations in some NVMe drives that are striped internally
(this target also works when stacked above the DM "striped" target).
- Various Documentation fixes and improvements.
- Misc cleanups and fixes across various DM infrastructure and targets

Pull xfs updates from Darrick Wong:
"This merge cycle, we're again some substantive changes to XFS.
Metadata verifiers have been restructured to provide more detail about
which part of a metadata structure failed checks, and we've enhanced
the new online fsck feature to cross-reference extent allocation
information with the other metadata structures. With this pull, the
metadata verification part of online fsck is more or less finished,
though the feature is still experimental and still disabled by
default.
We're also preparing to remove the EXPERIMENTAL tag from a couple of
features this cycle. This week we're committing a bunch of space
accounting fixes for reflink and removing the EXPERIMENTAL tag from
reflink; I anticipate that we'll be ready to do the same for the
reverse mapping feature next week. (I don't have any pending fixes for
rmap; however I wish to remove the tags one at a time.)
This giant pile of patches has been run through a full xfstests run
over the weekend and through a quick xfstests run against this
morning's master, with no major failures reported. Let me know if
there's any merge problems -- git merge reported that one of our
patches touched the same function as the i_version series, but it
resolved things cleanly.
Summary:
- Log faulting code locations when verifiers fail, for improved
diagnosis of corrupt filesystems.
- Implement metadata verifiers for local format inode fork data.
- Online scrub now cross-references metadata records with other
metadata.
- Refactor the fs geometry ioctl generation functions.
- Harden various metadata verifiers.
- Fix various accounting problems.
- Fix uncancelled transactions leaking when xattr functions fail.
- Prevent the copy-on-write speculative preallocation garbage
collector from racing with writeback.
- Emit log reservation type information as trace data so that we can
compare against xfsprogs.
- Fix some erroneous asserts in the online scrub code.
- Clean up the transaction reservation calculations.
- Fix various minor bugs in online scrub.
- Log complaints about mixed dio/buffered writes once per day and
less noisily than before.
- Refactor buffer log item lists to use list_head.
- Break PNFS leases before reflinking blocks.
- Reduce lock contention on reflink source files.
- Fix some quota accounting problems with reflink.
- Fix a serious corruption problem in the direct cow write code where
we fed bad iomaps to the vfs iomap consumers.
- Various other refactorings.
- Remove EXPERIMENTAL tag from reflink!"
