[Devel] [PATCH hci-8.1] ve/fs: let a container mount ext2 and ext3 through the ext4 driver

[no-reply at sashiko.virtuozzo.com]

> The ext4 driver also registers the ext2 and ext3 filesystem types, and
> those two carry none of the container flags ext4 itself has, so inside
> a container they are absent from /proc/filesystems and a mount of an
> ext2 or ext3 image fails with "unknown filesystem type", while the same
> image mounts as ext4. It is the same code either way, so give the two
> aliases the same flags; LTP formats its test devices as ext2 by default
> and every one of those tests breaks in a container on that mount.
