Oh, found it: it's

    (defcustom vc-ignore-dir-regexp
      ;; Stop SMB, automounter, AFS, and DFS host lookups.
      locate-dominating-stop-dir-regexp
      "Regexp matching directory names that are not under VC's control.
    The default regexp prevents fruitless and time-consuming attempts
    to determine the VC status in directories in which filenames are
    interpreted as hostnames."
      :type 'regexp
      :group 'vc)

used by VC.

I suggest you report it as a bug: vc-ignore-dir-regexp should only
"extend" locate-dominating-stop-dir-regexp but not override it (at
least by default).
