There isn't any way to tell a nohide from a non-nohide mount from the expots list. There are inconsistencies with the contents of /proc/mounts between OS versions (perhaps kernel version). There is no way to tell a nohide mounted filesystem from the output of /proc/mounts if it does happen to appear in it. *sigh* Ian - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
