From 8c792ea940499153732adea2ea4ca37f6999778f Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 10 Sep 2014 08:23:33 -0700 Subject: [PATCH] pnfs/blocklayout: don't set pages uptodate The core nfs code handles setting pages uptodate on reads, no need to mess with the pageflags outselves. Also remove a debug function to dump page flags.
