When naively running all kselftests on some systems, it was observed that the landlock selftest is quite picky and reports failures, even though the system is fine. Those two patches relax some tests to make them pass on older kernels: - The landlock ABI version is only "3" in recent kernels, so patch 1/2 relaxes the test to accept other numbers. - Older kernels or some defconfig based kernels might not implement the landlock syscall at all. Patch 2/2 catches this. I couldn't find an easy way to not check for the syscall availability in *every* test in base_test.c, short of not using TEST_HARNESS_MAIN at all. If someone has a better idea, I am all ears, especially as this approach will get quite annoying in fs_base.c.
