[LTP] [PATCH v4 0/7] mm/oom: extend the coverage of OOM

[Zhouping Liu <zliu@redhat.com>]

changed log from v1 to v2:
 1. added a new is_numa() function instead of ISNUMA global variable;
 2. added new patch to remove the prefix underscroe '_' of the
    internal function name;
 3. used SAFE_FILE_SCANF() instead of read_file().
 4. some cleanup...

changed log from v2 to v3:
 1. as Jan's suggestion, pass 'nodes=NULL' to get_allowed_nodes_arr()
    in is_numa(), and free 'nodes' variable when it passed a non-NULL
    value inside testoom().

changed log from v3 to v4:
 1. fixed some patch style error

The patch set updated all OOM testcases, and added a new testcase.

Inside old version, OOM only test MPOL_MBIND mempolicy in NUMA
system, and the combination of CPUSET, MEMCG & NUMA is complex,
and not clear. Also CPUSET is only used in NUMA system.

These patch set adjust them, now we can coverage the below tests:
 1) OOM under normal - oom01
 2) OOM under all mempolicy - oom02
 3) OOM under MEMCG (+ mempolicy) - oom03
 4) OOM under CPUSET (+ mempolicy)  - oom04
 5) OOM under CPUSET & MEMCG - oom05

Zhouping Liu (7):
  lib/mem: modified _gather_cpus() as _gather_node_cpus()
  mm/oom02: modified 'OOM for NUMA' as 'OOM for mempolicy'
  numa_helper: added a new function is_numa()
  mm/oom0[3|4]: added 'OOM for CPUSET' and moved 'OOM with MEMCG &
    numa' to oom03
  lib/mem: updated testoom() and oom() funcs
  mm/oom05: new testcase
  lib/mem: removed the prefix underscore '_' of the internal function
    name
