Btrfs: get rid of unused orphan infrastructure
Now that we don't keep long-standing reservations for orphan items, root->orphan_block_rsv isn't used. We can git rid of it, along with: - root->orphan_lock, which was used to protect root->orphan_block_rsv - root->orphan_inodes, which was used as a refcount for root->orphan_block_rsv - BTRFS_INODE_ORPHAN_META_RESERVED, which was used to track reservations in root->orphan_block_rsv - btrfs_orphan_commit_root(), which was the last user of any of these and does nothing else Reviewed-by: Nikolay Borisov <nborisov@suse.com> Signed-off-by: Omar Sandoval <osandov@fb.com> Signed-off-by: David Sterba <dsterba@suse.com>
