My apologies for not noticing this earlier, but we're often working
with older kernels.

mm: delete NR_PAGES_SCANNED and pgdat_reclaimable()
I was planning to use this number as a measure of how much work the
kernel was doing trying to reclaim pages (by comparing it, for
instance, to the number of pages actually swapped in). I am not even
sure how good a metric this would be. Does anybody have suggestions
for a good (or better) replacement?
Thanks!
