Pull yet more SPDX updates from Greg KH:
"Another round of SPDX header file fixes for 5.2-rc4
These are all more "GPL-2.0-or-later" or "GPL-2.0-only" tags being
added, based on the text in the files. We are slowly chipping away at
the 700+ different ways people tried to write the license text. All of
these were reviewed on the spdx mailing list by a number of different
people.
We now have over 60% of the kernel files covered with SPDX tags:
$ ./scripts/spdxcheck.py -v 2>&1 | grep Files
Files checked: 64533
Files with SPDX: 40392
Files with errors: 0
I think the majority of the "easy" fixups are now done, it's now the
start of the longer-tail of crazy variants to wade through"

Pull ADFS cleanups/fixes from Russell King:
"As a result of some of Al Viro's great work, here are a few cleanups
with fixes for adfs:
- factor out filename comparison, so we can be sure that
adfs_compare() (used for namei compare) and adfs_match() (used for
lookup) have the same behaviour.
- factor out filename lowering (which is not the same as tolower()
which will lower top-bit-set characters) to ensure that we have the
same behaviour when comparing filenames as when we hash them.
- factor out the object fixups, so we are applying all fixups to
directory objects in the same way, independent of the disk format.
- factor out the object name fixup (into the previously factored out
function) to ensure that filenames are appropriately translated -
for example, adfs allows '/' in filenames, which being the Unix
path separator, need to be translated to a different character,
which is normally '.' (DOS 8.3 filenames represent the . as a / on
adfs, so this is the expected reverse translation.)
- remove filename truncation; Al asked about this and apparently the
decision is to remove it. In any case, adfs's truncation was buggy,
so this rids us of that bug by removing the truncation feature.
- we now have only one location which adds the "filetype" suffix to
the filename, so there's no point that code being out of line.
- since we translate '/' into '.', an adfs filename of "/" or "//"
would end up being translated to "." and ".." which have special
meanings. In this case, change the first character to "^" to avoid
these special directory names being abused"
* tag 'for-rc-adfs' of git://git.armlinux.org.uk/~rmk/linux-arm:

iput_final() may wait for reahahead pages. The wait can cause deadlock.

In above example, truncate_inode_pages_range() waits for readahead pages
while holding s_mutex. ceph_check_caps() waits for s_mutex and blocks
OSD dispatch thread. Later OSD replies (for readahead) can't be handled.
ceph_check_caps() also may lock snap_rwsem for read. So similar deadlock
can happen if iput_final() is called while holding snap_rwsem.
In general, it's not good to call iput_final() inside MDS/OSD dispatch
threads or while holding any mutex.
The fix is introducing ceph_async_iput(), which calls iput_final() in
workqueue.

If a call to kobject_init_and_add() fails we should call kobject_put()
otherwise we leak memory.
Add call to kobject_put() in the error path of call to
kobject_init_and_add(). Please note, this has the side effect that the
release method is called if kobject_init_and_add() fails.

Pull yet more SPDX updates from Greg KH:
"Here is another set of reviewed patches that adds SPDX tags to
different kernel files, based on a set of rules that are being used to
parse the comments to try to determine that the license of the file is
"GPL-2.0-or-later" or "GPL-2.0-only". Only the "obvious" versions of
these matches are included here, a number of "non-obvious" variants of
text have been found but those have been postponed for later review
and analysis.
There is also a patch in here to add the proper SPDX header to a bunch
of Kbuild files that we have missed in the past due to new files being
added and forgetting that Kbuild uses two different file names for
Makefiles. This issue was reported by the Kbuild maintainer.
These patches have been out for review on the linux-spdx@vger mailing
list, and while they were created by automatic tools, they were
hand-verified by a bunch of different people, all whom names are on
the patches are reviewers"

This reverts most of commit b8eee0e90f97 ("lockd: Show pid of lockd for
remote locks"), which caused remote locks to not be differentiated between
remote processes for NLM.
We retain the fixup for setting the client's fl_pid to a negative value.

fs/adfs support for truncated filenames is broken, and there is a desire
not to support this into the future. Let's remove the fs/adfs support
for this.
Viro says:
"FWIW, the word from Linus had been basically "kill it off" on
truncation."
That being:
"Make it so. Make the rule be that d_hash() can only change the hash
itself, rather than the subtle special case for len that we had
because of legacy reasons.."

The ram pstore backend has always had the crash dumper frontend enabled
unconditionally. However, it was possible to effectively disable it
by setting a record_size=0. All the machinery would run (storing dumps
to the temporary crash buffer), but 0 bytes would ultimately get stored
due to there being no przs allocated for dumps. Commit 89d328f637b9
("pstore/ram: Correctly calculate usable PRZ bytes"), however, assumed
that there would always be at least one allocated dprz for calculating
the size of the temporary crash buffer. This was, of course, not the
case when record_size=0, and would lead to a NULL deref trying to find
the dprz buffer size:
BUG: unable to handle kernel NULL pointer dereference at (null)
...
IP: ramoops_probe+0x285/0x37e (fs/pstore/ram.c:808)
cxt->pstore.bufsize = cxt->dprzs[0]->buffer_size;
Instead, we need to only enable the frontends based on the success of the
prz initialization and only take the needed actions when those zones are
available. (This also fixes a possible error in detecting if the ftrace
frontend should be enabled.)

Set tfm to NULL on free_buf_for_compression() after crypto_free_comp().
This avoid a use-after-free when allocate_buf_for_compression()
and free_buf_for_compression() are called twice. Although
free_buf_for_compression() freed the tfm, allocate_buf_for_compression()
won't reinitialize the tfm since the tfm pointer is not NULL.

When a waiter is waked by CB_NOTIFY_LOCK, it will retry
nfs4_proc_setlk(). The waiter may fail to nfs4_proc_setlk() and sleep
again. However, the waiter is already removed from clp->cl_lock_waitq
when handling CB_NOTIFY_LOCK in nfs4_wake_lock_waiter(). So any
subsequent CB_NOTIFY_LOCK won't wake this waiter anymore. We should
put the waiter back to clp->cl_lock_waitq before retrying.

Commit b7dbcc0e433f "NFSv4.1: Fix a race where CB_NOTIFY_LOCK fails to wake a waiter"
found this bug. However it didn't fix it.
This commit replaces schedule_timeout() with wait_woken() and
default_wake_function() with woken_wake_function() in function
nfs4_retry_setlk() and nfs4_wake_lock_waiter(). wait_woken() uses
memory barriers in its implementation to avoid potential race condition
when putting a process into sleeping state and then waking it up.
