selftests/mm: hugetlb_fault_after_madv: improve test output
Let's improve the test output. For example, print the proper test result.
Install a SIGBUS handler to catch any SIGBUS instead of crashing the test
on failure.
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
