Submitted merge proposal to fix kernel-sru-review script in ubuntu-archive-tools:

Note lowlatency is now not built by the "main" 5.15 hwe, but all the configs remain inside this kernel. A separate source package of lowlatency-hwe will be added like in jammy. This is because we have now enabled lowlatency on arm64, and run out of buildtime on arm64 as it was timing out trying to complete building 4 arm64 flavours.

Note this means this tracker will not migrate, until lowlatency one is added, cause this meta drops packages, which are to be moved to linux-meta-lowlatency.

Comparing changes to master kernel are slightly interesting:

1) i am not sure why debian/scripts/misc/getabis removes fwinfo.builtin comparison and sorting, which is explicitely added in 22.22 build. Not critical will follow up.

2) aufs filesystem backport is still present as supported, which is a massive SAUCE patch, it does change security/security.c but only to simply export functions that are used by aufs.

3) otherwise security, lockdown, signing is the same.

sru-review done; instructing signing bot.

Getabi flip-flop is due to a missing cranky patch which has now been applied "APPLIED: [kteam-tools][PATCH] cranky: master -- getabis: Add fwinfo.builtin to the ABI"
