[PATCH] ext4: fix message in ext4_remount for rw-remount case

[Toshiyuki Okajima]

If there are some inodes in orphan list while a filesystem is being 
read-only mounted, we should recommend that pepole umount and then
mount it when they try to remount with read-write. But the current
message/comment recommends that they umount and then remount it.

ext4_remount:
	/*
	 * If we have an unprocessed orphan list hanging
	 * around from a previously readonly bdev mount,
	 * require a full umount/remount for now.
                          ^^^^^^^^^^^^^^
	 */
	if (es->s_last_orphan) {
		ext4_msg(sb, KERN_WARNING, "Couldn't "
				"remount RDWR because of unprocessed "
				"orphan inode list.  Please "
				"umount/remount instead");
                                 ^^^^^^^^^^^^^^

Hi,

I have just encountered this feature and I have a question:

How do I umount/mount if it's my root filesystem?
Is there anything I can do besides "the Microsoft way" (reboot)?

Only way that you can recover this situation by is to reboot
because the root filesystem cannot umount.
