This test case triggers a race between madvise(MADV_DONTNEED) and mmap() in a single huge page, which got stolen (while reserved).
Once the only page is stolen, the memory previously mmaped (and madvise(MADV_DONTNEED) got a SIGBUS when accessed.
I am not adding this test to the un_vmtests.sh scripts, since this test fails at upstream.
Oh. Is a fix for this in the pipeline? If so, I assume that once the fix is merged, we enable this test in run_vmtests?
The fix is not ready yet. As soon as the fix lands, I will enable the test in run_vmtests.
