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.

btrfs: fix lockups from btrfs_clear_path_blocking
