Nikolay Borisov committed 9bb8407f54f
btrfs: Make btrfs_find_name_in_backref return btrfs_inode_ref struct btrfs_find_name_in_backref returns either 0/1 depending on whether it found a backref for the given name. If it returns true then the actual inode_ref struct is returned in one of its parameters. That's pointless, instead refactor the function such that it returns either a pointer to the btrfs_inode_ref or NULL it it didn't find anything. This streamlines the function calling convention.
