Merge branch 'for-linus-4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
Pull btrfs fix from Chris Mason: "We have a btrfs quota regression fix. I merged this one on Thursday and have run it through tests against current master. Normally I wouldn't have sent this while you were finalizing rc6, but I'm feeding mosquitoes in the adirondacks next week, so I wanted to get this one out before leaving. I'll leave longer tests running and check on things during the week, but I don't expect any problems" * 'for-linus-4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: btrfs: qgroup: Fix a regression in qgroup reserved space.
