I think the right fix is to have lookups for "" do all the normal
processing when you open a file.
That is, it should do the translator startup, symlink, and other
special processing indicated at the comment "If this is translated,
start the translater..." in libdiskfs/dir-lookup.c (and, of course,
parallel code in the other implementations of dir-lookup).
This also requires a code audit for all the cases of null lookups (and
null retries, don't forget) to make sure that this is still the Right
Thing. I suspect it usually doesn't matter; when it does, O_NOTRANS
should be provided.
Essentially this amounts to moving the gotit: label earlier in the
file, and making sure that setup before the goto is still right.
