With unsuitable hugetlb page count: $ ./hugetlb_fault_after_madv TAP version 13 1..1 # [INFO] detected default hugetlb page size: 2048 KiB ok 2 # SKIP This test needs one and only one page to execute. Got 0 # Totals: pass:0 fail:0 xfail:0 xpass:0 skip:1 error:0 On a failure: $ ./hugetlb_fault_after_madv TAP version 13 1..1 not ok 1 SIGBUS behavior Bail out! 1 out of 1 tests failed On success: $ ./hugetlb_fault_after_madv TAP version 13 1..1 # [INFO] detected default hugetlb page size: 2048 KiB ok 1 SIGBUS behavior # Totals: pass:1 fail:0 xfail:0 xpass:0 skip:0 error:0 Link: https://lkml.kernel.org/r/20240926152044.2205129-3-david@redhat.com Signed-off-by: David Hildenbrand <david@redhat.com> Reviewed-by: Breno Leitao <leitao@debian.org> Tested-by: Mario Casquero <mcasquer@redhat.com> Cc: Shuah Khan <shuah@kernel.org> Cc: Shuah Khan <skhan@linuxfoundation.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
