The patchset provides both BPF LSM and SELinux implementations of the
hooks along with a BPF LSM test under tools/testing/selftests/bpf/.
If no one beats me to it, I plan to work on adding a test to the
selinux-testsuite as soon as I'm done dealing with other urgent
LSM/SELinux issues (io_uring CMD passthrough, SCTP problems, etc.); I
run these tests multiple times a week (multiple times a day sometimes)
against the -rcX kernels with the lsm/next, selinux/next, and
audit/next branches applied on top.  I know others do similar things.
