Subject: [GIT PULL] Btrfs deadlock fix

Hi Linus,

My for-linus branch:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus

Has a fix for a long standing deadlock that we've been trying to nail
down for a while.  It ended up being a bad interaction with the fair
reader/writer locks and the order btrfs reacquires locks in the btree.

Chris Mason (1) commits (+25/-15):
    btrfs: fix lockups from btrfs_clear_path_blocking

Total: (1) commits (+25/-15)
