Merge branch 'for-linus-4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
Pull btrfs updates from Chris Mason:
"We have a lot of subvolume quota improvements in here, along with big
piles of cleanups from Dave Sterba and Anand Jain and others.
Josef pitched in a batch of allocator fixes based on production use
here at FB. We found that mount -o ssd_spread greatly improved our
performance on hardware raid5/6, but it exposed some CPU bottlenecks
in the allocator. These patches make a huge difference"
