From a877ee03ac010ded434b77f7831f43cbb1fcc60f Mon Sep 17 00:00:00 2001 From: Bryan Schumaker Date: Fri, 7 Oct 2011 13:41:15 -0400 Subject: [PATCH] vfs: add "device" tag to /proc/self/mountstats nfsiostat was failing to find mounted filesystems on kernels after 2.6.38 because of changes to show_vfsstat() by commit c7f404b40a3665d9f4e9a927cc5c1ee0479ed8f9. This patch adds back the "device" tag before the nfs server entry so scripts can parse the mountstats file correctly.
