FOSS activity in January 2024

I fixed a bug in my merge request adding the rsync method to dput-ng. (This has now been merged and included in the dput 1.38 release.)
I updated the Linux kernel packages in various Debian suites:
- (LTS) buster: Updated linux (4.19) to upstream version 4.19.304, uploaded it, and issued DLA-3710-1.
- (LTS) buster: Updated linux-5.10 to the latest security update for bullseye, uploaded it, and issued DLA-3711-1.
- bullseye-backports: Updated linux to the latest security update for bookworm, and uploaded it.
- bookworm-backports: Updated linux to the latest version in sid, but didn't upload it as that version is not yet in testing.
I uploaded kernel-wedge to bookworm-backports as it will be needed by later updates to the linux backport.
I reviewed the enablement of bcachefs in Debian.
I updated the Debian kernel upload checklist in line with recent changes to kernel ABI handling.
I reviewed (again) Bastian's proposal to change the use of Git branches for the Debian kernel package.
I discussed the support status of armel in the Debian kernel package.
