As a reminder, the LSM layer, just like the rest of the kernel, has no plans to provide any level of consideration or support for out-of-tree kernel code. LSMs which are not part of the upstream Linux kernel are not our concern here; if they fail to work with the syscall and/or LSM stacking changes merged, that should not be considered a blocker to upstream development. -- paul-moore.com
