regression: bfs endianness bug
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").
