Subject: vm_total_pages and page-writeback.c:total_pages
Date: Tue, 22 Aug 2006 16:53:23 -0700 [thread overview]
Message-ID: <1156290803.6479.129.camel@linuxchandra> (raw)
Hello,
I was looking at page-writeback.c and found that there is a static
variable "total_pages", which is same as the global variable
"vm_total_pages" except that "total_pages" is not updated when new pages
are brought in through memory hotplug.
Looking at the usage of "total_pages", it doesn't look intentional. Can
somebody tell if it is the intentional or it a bug that needs to be
fixed ?
Under the same context, "ratelimit_pages" in page-writeback.c is
recalculated every time CPU is hot added/removed. But there is no
recalculation happening when new memory pages are hot added. This also
doesn't seem to be right. Comments ?
regards,
chandra
