Hello.

I have problem with xfs_bmbt_ptr_t from xfs_dinode_t structure. I don't know how to interprete filesystem block number (i use documentation from http://oss.sgi.com/projects/xfs/papers/xfs_filesystem_structure.pdf , page 34).

In detail

I have b-tree extent list -> i read some informations about this b-tree (so i have filesystem block number)
How can i allocate block from filesystem block number?

Regards
Damian
