ext2: show all mount options
Using mtab is problematic for various reasons, one of them is that unprivileged mounts won't turn up in there. So we want to get rid of it, and use /proc/mounts instead. But most filesystems are lazy, and are not showing all mount options. Which means, that without mtab, the user won't be able to see some or all of the options. It would be nice if the generic code could remember the mount options, and show them without the need to add extra code to filesystems. But this is not easy, because different filesystems handle mount options given options, and not tough the rest. This is not taken into account by mount(8) either, so /etc/mtab will be broken in this case. This series fixes up ->show_options() in ext[234].
