IMHO that behavior for file_name_lookup_under is clearly wrong,
and perhaps dangerously so.
The original point of using something that resolves to dir_lookup("/",...)
rather than a lookup of "." is that it should not require actual lookup
permission, but should still require that it be a directory

Mmm, I'd say "almost". That line means starting from directory one
should look at directory /, and what __hur

Another bug detected by gnulib:
fdopendir(creat("file",0600)) returns a DIR* pointer rather than NULL;
subsequent attempts to use that pointer with readdir() then fail with
ENOTDIR. But POSIX requires that the fdopendir fail with ENOTDIR up front.

fdopendir uses __file_name_lookup_under (port, "/", O_DIRECTORY | O_NOTRANS, 0)
which I think is exactly right. Something has gotten broken lower down if
that is not doing it.
Thanks,
Roland
