Subject: removing mm->rss and mm->anon_rss from kernel?
Date: Sat, 6 Nov 2004 01:28:16 -0800 (PST) [thread overview]
Message-ID: <Pine.LNX.4.58.0411060120190.22874@schroedinger.engr.sgi.com> (raw)
In-Reply-To: <418C55A7.9030100@yahoo.com.au>
My page scalability patches need to make rss atomic and now with the
addition of anon_rss I would also have to make that atomic.
But when I looked at the code I found that the only significant use of
both is in for proc statistics. There are 3 other uses in mm/rmap.c where
the use of mm->rss may be replaced by mm->total_vm.
So I removed all uses of mm->rss and anon_rss from the kernel and
introduced a bean counter count_vm() that is only run when the
corresponding /proc file is used. count_vm then runs throught the vm
and counts all the page types. This could also add additional page types to our
statistics and solve some of the consistency issues.
The patch is by no means perfect. If you think this is worth pursuing then
I will finish the support for other archs and deal with the locking
issues etc. This patch may also remove hot spot issues that may arise with
the use of these two variables and so is of interest to us.
But a kernel with this patch boots fine and the statistics in /proc look
still okay (its late though....)
