I have merged the following commits to master and v5.8 in upstream xz.git: ee75c76958dd Landlock: Cache the ABI version 2b2652e914b1 Landlock: Workaround a bug in RHEL 9 kernel 8bb516887c19 Landlock: Add missing #ifdefs
They will be in xz 5.8.2 unless Red Hat fixes their kernel soon. I don't have an opinion if Debian should include those commits in trixie. Debian itself doesn't need them, but without them one cannot run trixie's xz in a container on RHEL 9's current kernel. -- Lasse Collin
