Merge tag 'for-4.15-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs fixes from David Sterba:
"This contains a few fixes (error handling, quota leak, FUA vs
nobarrier mount option).
There's one one worth mentioning separately - an off-by-one fix that
leads to overwriting first byte of an adjacent page with 0, out of
bounds of the memory allocated by an ioctl. This is under a privileged
part of the ioctl, can be triggerd in some subvolume layouts"
