Do you have patch 21/24 applied?  In 26-rc5-mm1, I see the
noreclaim_pgs_* vmstat items.  They're in the patch 21 you just posted,
as well.

Again, we might decide to drop that patch from the merge.  I found the
stats useful during debug and test, but I don't know that they provide
any value in the longer term.
