Subject: [PATCH 0/3] mm: mlock: elaborate mlock selftest case and fix one bug identified

From: Simon Guo <wei.guo.simon@...il.com>

The original mlock self tests are far from completed and David suggests
to elaborate that.

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
