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

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
