Pull btrfs fix from David Sterba:
"This is the fix for sleeping in a locked section bug reported by Dave
Jones, caused by a patch dependence in development and pulled
branches.
I picked the existing patch over the fixup that Filipe sent, as it's a
bit more generic fix. I've verified it with a specific test case, some
rsync stress and one round of fstests"
