[patch 0/4] memcg: operate on page quantities internally

[Johannes Weiner]

Hi,

this patch set converts the memcg charge and uncharge paths to operate
on multiples of pages instead of bytes.  It already was a good idea
before, but with the merge of THP we made a real mess by specifying
huge pages alternatingly in bytes or in number of regular pages.

If I did not miss anything, this should leave only res_counter and
user-visible stuff in bytes.  The ABI probably won't change, so next
up is converting res_counter to operate on page quantities.
