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).
But what'r the challenge(s) to have ref count in the
btrfs_file_extent_item ? any thoughts ?
Thanks, Anand
