BFS_FILEBLOCKS() expects struct bfs_inode * (on-disk data, with little-endian
fields), not struct bfs_inode_info * (in-core stuff, with host-endian ones).
It's a macro and fields with the right names are present in bfs_inode_info,
so it compiles, but on big-endian host it gives bogus results.
Introduced in commit f433dc56344cb72cc3de5ba0819021cec3aef807 (Fixes to the
BFS filesystem driver).
