Bug Description

SRU Justification

[Impact]

The erofs.ko module (CONFIG_EROFS) is currently shipped in linux-modules-extra. This makes it hard to pull in via the linux-virtual package, it can only come from the linux-generic one that also pulls in the firmware and everything else needed for baremetal, and that serves no purpose in a qemu VM. This stops VMs using these kernels from using the erofs filesystem. Erofs is a modern alternative to squashfs that supports more features such as ACLs. The following LPC presentation has more details on erofs and its advantages over squashfs: https://youtu.be/jt-hp_LtSBc.

A user launching a VM using the linux-virtual kernel image is not able to mount erofs filesystems due to the lack of this kconfig. We make extensive use of erofs in systemd's upstream CI, which is running on Github Actions, which uses Jammy, so it would be great to have this backported.

[Fix]

Please consider moving this module to linux-modules.

These are already enabled in the 'main' kernel config, and in other distros. In Debian/Archlinux/Fedora it is a (core) module that is built by default.

To verify this works, it is sufficient to create an erofs filesystem with mkfs.erofs and verify that it can be mounted:

$ mkdir sources
$ echo abcde > sources/file
$ mkfs.erofs erofs sources
$ mount erofs mnt --mkdir
$ ls mnt
file

Without this module installed and loaded, the mount will fail. Once enabled, it will succeed.

[Test]

1. pull built linux-modules packages for architectures with do_extras_package
   set to true;
2. extract the deb and check if erofs kernel module file exists:

   $ dpkg-deb -R linux-modules-*.deb .
   $ find . -name erofs.ko\*

[Regression Potential]

Moving a module from a less-common to a more-common package should not have any negative side effects. The main effect will be a little more disk space used by the more common package, whether the module is in use or not. There will also be more functionality available in the default installation, which means a slightly increased surface and possibility of new bugs in case it gets used.
