I'm having difficulties with the semantics of the real_lookup routine in
fs/iname.c. I have a lookup in my filesystem that posts a message on a
message queue, and the lookup gets handled by another part of the
filesystem. This other part adds the dentry to the dcache with d_add and
wakes up the lookup. lookup then does a d_lookup to get the dentry.

The problem is that the lookup routine has to fill in the dentry that
real_lookup provided. How do I get the information over from my own
dentry? memcpy is not very good, since it make pointers point to the wrong
places.
