I think some of the comments are worth addressing, especially:

Patch 4:
Using BUF_SIZE in the allocation helpers is wrong, we should use the
actual page size.

Patch 6:
Zero initialization of zw_allocation.

But yeah as Andrew said, it may be worth waiting for memcg maintainers
to take a look before sending a new version.
