Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
Pull btrfs fixes from Chris Mason:
"We have a small collection of fixes in my for-linus branch.
The big thing that stands out is a revert of a new ioctl. Users
haven't shipped yet in btrfs-progs, and Dave Sterba found a better way
to export the information"
