--- Comment #5 from Jilles Tjoelker <jil...@freebsd.org> ---
As it is now, KERN_PROC_FILEDESC is designed for debugging only. The namecache
is best-effort. See for example SVN r275897, which states that newly created
files are deliberately not entered into the namecache (as part of a change to
enter core dump filenames into the namecache).
A second problem is that KERN_PROC_FILEDESC processes all file descriptors at
once and may therefore be slow.
I think directory file descriptors always know their names because directories
have a single "..", all the way up to the root.
