If 'btrfs_file_extent_item' can contain the ref count it would solve the current problem quite easily. (problem is that, its of n * n searches to know data extents with its ref for a given subvol).
Just considering btrfs_file_extent_item is not enough, because we should consider metadata(as i have said before).
But what'r the challenge(s) to have ref count in the btrfs_file_extent_item ? any thoughts ?
Haven't thought a better idea yet.
