*** DEADLOCK ***
Commit 084b6e7c7607 ("btrfs: Fix a lockdep warning when running xfstest.") tried
to fix a similar one that has the exactly same warning, but with that, we still
run to this.
The above lock chain comes from
btrfs_commit_transaction
->btrfs_run_delayed_items
...
->__btrfs_update_delayed_inode
...
->__btrfs_cow_block
...
->find_free_extent
->cache_block_group
->load_free_space_cache
->btrfs_readpages
->submit_one_bio
...
->__btrfs_map_block
->btrfs_dev_replace_lock
However, with high memory pressure, tasks which hold dev_replace.lock can
be interrupted by kswapd and then kswapd is intended to release memory occupied
by superblock, inodes and dentries, where we may call evict_inode, and it comes
to
[ 1226.652955] [<ffffffff81458735>] __btrfs_release_delayed_node+0x45/0x1d0
[ 1226.652955] [<ffffffff81459e74>] btrfs_remove_delayed_node+0x24/0x30
[ 1226.652955] [<ffffffff8140c5fe>] btrfs_evict_inode+0x34e/0x700
delayed_node->mutex may be acquired in __btrfs_release_delayed_node(), and it leads
to a ABBA deadlock.
To fix this, we can use "blocking rwlock" used in the case of extent_buffer, but
things are simpler here since we only needs read's spinlock to blocking lock.
With this, btrfs/011 no more produces warnings in dmesg.

We will sometimes start background flushing the various enospc related things
(delayed nodes, delalloc, etc) if we are getting close to reserving all of our
available space. We don't want to do this however when we are actually using
this space as it causes unneeded thrashing. We currently try to do this by
checking bytes_used >= thresh, but bytes_used is only part of the equation, we
need to use bytes_reserved as well as this represents space that is very likely
to become bytes_used in the future.
My tracing tool will keep count of the number of times we kick off the async
flusher, the following are counts for the entire run of generic/027
No Patch Patch
avg: 5385 5009
median: 5500 4916
We skewed lower than the average with my patch and higher than the average with
the patch, overall it cuts the flushing from anywhere from 5-10%, which in the
case of actual ENOSPC is quite helpful. Thanks,

truncate_space_check is using btrfs_csum_bytes_to_leaves() but forgetting to
multiply by nodesize so we get an actual byte count. We need a tracepoint here
so that we have the matching reserve for the release that will come later. Also
add a comment to make clear what the intent of truncate_space_check is.

I'm writing a tool to visualize the enospc system in order to help debug enospc
bugs and I found weird data and ran it down to when we update the global block
rsv. We add all of the remaining free space to the block rsv, do a trace event,
then remove the extra and do another trace event. This makes my visualization
look silly and is unintuitive code as well. Fix this stuff to only add the
amount we are missing, or free the amount we are missing. This is less clean to
read but more explicit in what it is doing, as well as only emitting events for
values that make sense. Thanks,

For a non-existent device, old code bypasses adding it in dev's reada
queue.
And to solve problem of unfinished waitting in raid5/6,
commit 5fbc7c59fd22 ("Btrfs: fix unfinished readahead thread for
raid5/6 degraded mounting")
adding an exception for the first stripe, in short, the first
stripe will always be processed whether the device exists or not.
Actually we have a better way for the above request: just bypass
creation of the reada_extent for non-existent device, it will make
code simple and effective.

Reada background works is not designed to finish all jobs
completely, it will break in following case:
1: When a device reaches workload limit (MAX_IN_FLIGHT)
2: Total reads reach max limit (10000)
3: All devices don't have queued more jobs, often happened in DUP case
And if all background works exit with remaining jobs,
btrfs_reada_wait() will wait indefinetelly.
Above problem is rarely happened in old code, because:
1: Every work queues 2x new works
So many works reduced chances of undone jobs.
2: One work will continue 10000 times loop in case of no-jobs
It reduced no-thread window time.
But after we fixed above case, the "undone reada extents" frequently
happened.
Fix:
Check to ensure we have at least one thread if there are undone jobs
in btrfs_reada_wait().

Reada creates 2 works for each level of tree recursively.
In case of a tree having many levels, the number of created works
is 2^level_of_tree.
Actually we don't need so many works in parallel, this patch limits
max works to BTRFS_MAX_MIRRORS * 2.
The per-fs works_counter will be also used for btrfs_reada_wait() to
check is there are background workers.

No need to decrease dev->reada_in_flight in __readahead_hook()'s
internal and reada_extent_put().
reada_extent_put() have no chance to decrease dev->reada_in_flight
in free operation, because reada_extent have additional refcnt when
scheduled to a dev.
We can put inc and dec operation for dev->reada_in_flight to one
place instead to make logic simple and safe, and move useless
reada_extent->scheduled_for to a bool flag instead.

We can't release reada_extent earlier than __readahead_hook(), because
__readahead_hook() still need to use it, it is necessary to hode a refcnt
to avoid it be freed.
Actually it is not a problem after my patch named:
Avoid many times of empty loop
It make reada_extent in above line include at least one reada_extctl,
which keeps additional one refcnt for reada_extent.
But we still need this patch to make the code in pretty logic.

We can see following loop(10000 times) in trace_log:

Reason:
If more than one user trigger reada in same extent, the first task
finished setting of reada data struct and call reada_start_machine()
to start, and the second task only add a ref_count but have not
add reada_extctl struct completely, the reada_extent can not finished
all jobs, and will be selected in __reada_start_machine() for 10000
times(total times in __reada_start_machine()).
Fix:
For a reada_extent without job, we don't need to run it, just return
0 to let caller break.

reada_zone->end is end pos of segment:
end = start + cache->key.offset - 1;
So we need to use "<=" in condition to judge is a pos in the
segment.
The problem happened rearly, because logical pos rarely pointed
to last 4k of a blockgroup, but we need to fix it to make code
right in logic.

- Compilation fixes on SPEAR, and U8500 thermal drivers.
- RCAR thermal driver now recognizes OF-thermal based thermal zones.
- Small code rework on OF-thermal.
- These change have been CI tested using KernelCI bot [1,2]. \o/
I am taking over on Rui's behalf while he is out. Happy New Chinese
Year!

The 'umidi' object will be free'd on the error path by snd_usbmidi_free()
when tearing down the rawmidi interface. So we shouldn't try to free it
in snd_usbmidi_create() after having registered the rawmidi interface.

Merge fixes from Andrew Morton:
"10 fixes"
The lockdep hlist conversion is in the locking tree too, waiting for the
next merge window. Andrew thought it should go in now. I'll take it,
since it fixes a real problem and looks trivially correct (famous last
words).
* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
arch/x86/Kconfig: CONFIG_X86_UV should depend on CONFIG_EFI
mm: fix pfn_t vs highmem
kernel/locking/lockdep.c: convert hash tables to hlists
mm,thp: fix spellos in describing __HAVE_ARCH_FLUSH_PMD_TLB_RANGE
mm,thp: khugepaged: call pte flush at the time of collapse
mm/backing-dev.c: fix error path in wb_init()
