viro sayeth:

  I've run allmodconfig builds on a bunch of target, FWIW (essentially the
  same patch).  Note that these includes are recent addition caused by added
  inline function that had since then become a define.  So while I agree with
  your comments in general, in _this_ case it's pretty safe.

  The commit that had done it is 3062fc67da
  ("memcontrol: move mm_cgroup to header file") and the switch to #define
  is in commit 60c12b1202 ("memcontrol: add
  vm_match_cgroup()") (BTW, that probably warranted mentioning in the
  changelog of the latter).
