Subject: page_referenced() and VM_LOCKED
Date: Thu, 15 Nov 2007 20:25:45 -0800	[thread overview]
Message-ID: <473D1BC9.8050904@google.com> (raw)

page_referenced_file() checks for the vma to be VM_LOCKED|VM_MAYSHARE
and adds returns 1. We don't do the same in page_referenced_anon(). I
would've thought the point was to treat locked pages as active, never
pushing them into the inactive list, but since that's not quite what's
happening I was hoping someone could give me a clue.

	Thanks,
	-- Ethan
