And there's another issue: when running the migration test individually,
private_anon_htlb gets skipped. I guess it's because the previous test
is restoring the HugeTLB state:
It could be.
I pushed the updated version that has the fixes for both zombie and
signal issues:
https://git.kernel.org/pub/scm/linux/kernel/git/rppt/linux.git/log/?h=mm-selftest/v3
Would be great if you can test it in your setup.
This works! Both issues are fixed: the migration test completes w/o
hanging and when I run it individually all tests run.
Thanks for confirming!
One last question: should we munmap() the mappings in this test? Though
I understand this goes beyond your series goal.
We could, but the tests _exit() anyway as a part of kselftest_harness, so
it does not really matter.
OK. Just to clarify that I meant exercising the munmap() path, not that
we're not freeing resources. But if we know that _exit() is sufficient
for this, then it's fine.
