bug#32520: 26.1; problem with CIFS mounts

[emacs]

> Does it help to add /cifs to locate-dominating-stop-dir-regexp?

Doesn't seem to, if I did it correctly.

My locate-dominating-stop-dir-regexp was:
  "\\`\\(?:[\\/][\\/][^\\/]+[\\/]\\|/\\(?:net\\|afs\\|\\.\\.\\.\\)/\\)\\'"
and I made it be:
  
"\\`\\(?:[\\/][\\/][^\\/]+[\\/]\\|/\\(?:net\\|cifs\\|afs\\|\\.\\.\\.\\)/\\)\\'"

I've tried it in my current emacs session, and on a new
emacs -Q -nw session.

I do nfs mounts under /net, and visiting files or
directories under that don't log any errors.
