[LTP] [PATCH v4 0/5] controllers/memcg: fixes for newer kernels

[Krzysztof Kozlowski]

Hi,

Changes since v3:
1. Patch 4/5: Include per-CPU memory as well in group limits.

Changes since v2:
1. Patch 1/5: Define MEM_USAGE_RANGE and explain it.
2. Patch 3/5: Use PAGESIZES to explain it is the batch accounting.
3. Patch 4/5: Add to this patchset (previously sent separately, no
   dependencies on others).
4. Patch 5/5: New patch, fixes additional difference, usually of 2-3
   pages coming from the kernel.
