Revision 51090c5d6de08cfc86b2d861775dedddd9a2c023 authored by Linus Torvalds on 10 December 2017, 16:30:04 UTC, committed by Linus Torvalds on 10 December 2017, 16:30:04 UTC
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" * tag 'for-4.15-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: btrfs: Fix possible off-by-one in btrfs_search_path_in_tree Btrfs: disable FUA if mounted with nobarrier btrfs: fix missing error return in btrfs_drop_snapshot btrfs: handle errors while updating refcounts in update_ref_for_cow btrfs: Fix quota reservation leak on preallocated files
