But VFS wants the directory reading task to return a list of files with
corresponding inodes numbers. Reiser4, in this case, has to check out the
tree and read the directory entries, but what about resolving a simple file
path : does VFS in this case want the files and subdirectory listings of
every directory the path consists in, or does VFS directly ask Reiser4 to
resolve the whole path ?
What does Reiser4 do to improve the path resolving and directory listing
performance ? Do you implement another cache even if the VFS allready got
one ?

That would be a great thing ;)
