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.
