Merge branch 'for-linus-unmerged' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-unstable
* 'for-linus-unmerged' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-unstable: (45 commits) Btrfs: fix __btrfs_map_block on 32 bit machines btrfs: fix possible deadlock by clearing __GFP_FS flag btrfs: check link counter overflow in link(2) btrfs: don't mess with i_nlink of unlocked inode in rename() Btrfs: check return value of btrfs_alloc_path() Btrfs: fix OOPS of empty filesystem after balance Btrfs: fix memory leak of empty filesystem after balance Btrfs: fix return value of setflags ioctl Btrfs: fix uncheck memory allocations btrfs: make inode ref log recovery faster Btrfs: add btrfs_trim_fs() to handle FITRIM Btrfs: adjust btrfs_discard_extent() return errors and trimmed bytes Btrfs: make btrfs_map_block() return entire free extent for each device of RAID0/1/10/DUP Btrfs: make update_reserved_bytes() public btrfs: return EXDEV when linking from different subvolumes Btrfs: Per file/directory controls for COW and compression Btrfs: add datacow flag in inode flag btrfs: use GFP_NOFS instead of GFP_KERNEL Btrfs: check return value of read_tree_block() btrfs: properly access unaligned checksum buffer ... Fix up trivial conflicts in fs/btrfs/volumes.c due to plug removal in the block layer.
