Subject[PATCH 00/14] mm: memcontrol: account socket memory in unified hierarchy v4-RESEND
Date
Hi Andrew,

there was some build breakage in CONFIG_ combinations I hadn't tested
in the last revision, so here is a fixed-up resend with minimal CC
list. The only difference to the previous version is a section in
memcontrol.h, but it accumulates throughout the series and would have
been a pain to resolve on your end. So here goes. This also includes
the review tags that Dave and Vlad had sent out in the meantime.

Difference to the original v4:
