The recently released stable version 3.18.125 introduced a deadlock
because dm_get_live_table() is called twice within __dm_destroy().
The backported commit e1db66a5 "dm: fix AB-BA deadlock in
__dm_destroy()" doesn't *move* the dm_get_live_table() call from
before the mutex_lock(), as the original commit 2a708cff does, but
instead *adds* a new dm_get_live_table() call after the mutex_lock().
The two dm_get_live_table() calls result in a deadlock:

Removing the original dm_get_live_table() call from before the
mutex_lock() prevents the deadlock.
Thanks for maintaining 3.18!
PS Greg, Was this a subtle attempt to get someone to speak up and say
"I am using this!" as you requested in the 3.18.125 release
announcement? ;)

Subject: [PATCH] Btrfs: fix use-after-free during inode eviction
At inode.c:evict_inode_truncate_pages(), when we iterate over the
inode's extent states, we access an extent state record's "state" field
after we unlocked the inode's io tree lock. This can lead to a
use-after-free issue because after we unlock the io tree that extent
state record might have been freed due to being merged into another
adjacent extent state record (a previous inflight bio for a read
operation finished in the meanwhile which unlocked a range in the io
tree and cause a merge of extent state records, as explained in the
comment before the while loop added in commit 6ca0709756710 ("Btrfs: fix
hang during inode eviction due to concurrent readahead")).
Fix this by keeping a copy of the extent state's flags in a local
variable and using it after unlocking the io tree.

This could result in a really bad case where we do something like
evict
evict_refill_and_join
btrfs_commit_transaction
btrfs_run_delayed_iputs
evict
evict_refill_and_join
btrfs_commit_transaction
... forever
We have plenty of other places where we run delayed iputs that are much
safer, let those do the work.

Subject: [PATCH] btrfs: don't run delayed_iputs in commit
This could result in a really bad case where we do something like
evict
evict_refill_and_join
btrfs_commit_transaction
btrfs_run_delayed_iputs
evict
evict_refill_and_join
btrfs_commit_transaction
... forever
We have plenty of other places where we run delayed iputs that are much
safer, let those do the work.

Subject: [PATCH] btrfs: reset max_extent_size properly
If we use up our block group before allocating a new one we'll easily
get a max_extent_size that's set really really low, which will result in
a lot of fragmentation. We need to make sure we're resetting the
max_extent_size when we add a new chunk or add new space.
