    Pull autofs update from Christian Brauner:
     "Prevent futile mount triggers in private mount namespaces.

      Fix a problematic loop in autofs when a mount namespace contains
      autofs mounts that are propagation private and there is no
      namespace-specific automount daemon to handle possible automounting.

      Previously, attempted path resolution would loop until MAXSYMLINKS was
      reached before failing, causing significant noise in the log.

     The fix adds a check in autofs ->d_automount() so that the VFS can
     immediately return EPERM in this case. Since the mount is propagation
     private, EPERM is the most appropriate error code"
