Subject: [GIT PULL] Btrfs

Hi Linus,

We have some fixes queued up in my for-linus-4.5 branch:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus-4.5

Dave had a small collection of fixes to the new free space tree code,
one of which was keeping our sysfs files more up to date with feature
bits as different things get enabled (lzo, raid5/6, etc).

I should have kept the sysfs stuff for rc3, since we always manage to
trip over something.  This time it was GFP_KERNEL from somewhere that is
NOFS only. Instead of rebasing it out I've put a revert in, and we'll
fix it properly for rc3.

Otherwise, Filipe fixed a btrfs DIO race and Qu Wenruo fixed up a
use-after-free in our tracepoints that Dave Jones reported.
