Subject: [GIT PULL] Landlock fix for v6.12-rc7 #2

Hi Linus,

This PR fixes issues in the Landlock's sandboxer sample and documentation,
slightly refactors helpers (required for ongoing patch series), and improve/fix
a feature merged in v6.12 (signal and abstract UNIX socket scoping).

Please pull these changes for v6.12-rc7 (or rc8, if any).  These commits merge
cleanly with your master branch.  The kernel code has been tested in the latest
linux-next releases for a few weeks, but I updated the last three patches with
cosmetic changes according to reviews.

Test coverage for security/landlock is 92.5% of 1129 lines according to
gcc/gcov-14, and it was 92.8% of 1134 lines before this PR.

Regards,
 Mickaël
