Hello,

FYI:

In fact just tried yesterday to use mount option "iversion" on 3.4-rc5
and it seems to work without
 +       sb->s_flags |= MS_I_VERSION;

I checked that following is really happening in btrfs_update_time():

	if (sync_it & S_VERSION)
		inode_inc_iversion(inode);

I also put some prints to btrfs_mount and remount and see that
MS_I_VERSION is not set there yet.

Somehow magically it gets set...
