[PATCH -mm 01/15] FYI: vmstats are "off-by-one"

From: Rik van Riel
Date: Mon Apr 28 2008 - 14:24:03 EST


PATCH - add vmstat_test for NR_WRITEBACK_TEMP

Against: 2.6.25-rc8-mm2 [also missing in '.25-mm1]

/proc/vmstat output after "nr_vmscan_write" are off-by-one
because of missing test for NR_WRITEBACK_TEMP added to
mmzone.h. Apparently missing from:

mm-add-nr_writeback_temp-counter.patch

in -mm tree.

Andrew,

you may already have this patch. I am posting it in this
series to help other testers of the code.

Rik, Kosaki-san:

Here's a patch that I'm going to post to Andrew and the mailing lists.
I noticed that the noreclaim events were off by one. Missing
vmstat_text in 25-rc8-mm* and 25-mm1.

I have this in my tree as a 25-*mm* "hotfix"--i.e., before any of our
patches. It causes a couple of 1 one offsets but no patch conflicts.

Lee
