[GIT PULL] Btrfs fixes

[Chris Mason <clm@fb.com>]

Hi Linus,

We have a small queue of btrfs fixes in my for-linus branch:

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

None of these are huge, but my commit does fix a regression from 3.18
that could cause lost files during log replay.

This also adds Dave Sterba to the list of Btrfs maintainers.  It doesn't
mean we're doing things differently, but Dave has really been helping
with the maintainer workload for years.

Chris Mason (2) commits (+9/-0):
    Btrfs: don't delay inode ref updates during log replay (+8/-0)
