    usr.sbin/autofs: Workaround namecache bug after unmount
    
    autounmountd gets affected by the namecache bug mentioned in
    https://bugs.dragonflybsd.org/issues/2908.
    
    This can be worked around by stat(2) (or any syscall that resolves
    the name once again) after unmount failed with EBUSY.
    
    Without this workaround, a process at automounted filesystem will
    see ENOTCONN after autounmountd's attempt to unmount. This must
    not be removed until the namecache bug is fixed.
