Hi Josef,
commit 660d3f6cde552323578b85fc5a09a6742f1fe804
Author: Josef Bacik

Btrfs: fix how we do delalloc reservations and how we free reservations on
error
introduced possible deadlock. According to comment before
btrfs_page_mkwrite(), that function
xfstests 218 complains that btrfs defrags a file partially:
After: 1
Write backwards sync, but contiguous - should defrag to 1 extent
Before: 10
-After: 1
+After: 2
To fix this, we need to set max_to_defrag count properly.

Btrfs progs has a defragment tool, so we can test 218 on btrfs now.

Thanks Andi, I've queued this up to a btrfs snappy

Hi everyone,
Ilya reworked the new balancing ioctls a little, so I've rebased the
integration branch to include his new code. Sorry for the trouble.
