Merge branch 'for-linus-min' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
Pull the minimal btrfs branch from Chris Mason: "We have a use-after-free in there, along with errors when mount -o discard is enabled, and a BUG_ON(we should compile with UP more often)." * 'for-linus-min' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: Btrfs: use commit root when loading free space cache Btrfs: fix use-after-free in __btrfs_end_transaction Btrfs: check return value of bio_alloc() properly Btrfs: remove lock assert from get_restripe_target() Btrfs: fix eof while discarding extents Btrfs: fix uninit variable in repair_eb_io_failure Revert "Btrfs: increase the global block reserve estimates"
