The patch set expand mlock selftest case by randomly mlock/mlock2 on given memory region. It covers both under MLOCK rlimit and exceed MLOCK rlimit case. During the testing, one bug was identified (introduced by my previous patch and sorry for that). Fix is included in this patch set. Simon Guo (3): mm: mlock: correct a typo in count_mm_mlocked_page_nr() for caculate VMLOCKED pages selftest: move seek_to_smaps_entry() out of mlock2-tests.c selftests: expanding more mlock selftest mm/mlock.c | 6 +- tools/testing/selftests/vm/Makefile | 4 +- tools/testing/selftests/vm/mlock-intersect-test.c | 76 ------ tools/testing/selftests/vm/mlock-random-test.c | 293 ++++++++++++++++++++++ tools/testing/selftests/vm/mlock2-tests.c | 42 ---- tools/testing/selftests/vm/mlock2.h | 43 ++++ 6 files changed, 342 insertions(+), 122 deletions(-) delete mode 100644 tools/testing/selftests/vm/mlock-intersect-test.c create mode 100644 tools/testing/selftests/vm/mlock-random-test.c -- 1.8.3.1
