Subject: [PATCH 1/2] smaps: show VM_SOFTDIRTY flag in VmFlags line
Date: Fri, 4 Oct 2013 15:02:14 -0400 [thread overview]
Message-ID: <1380913335-17466-1-git-send-email-n-horiguchi@ah.jp.nec.com> (raw)
This flag shows that soft dirty bit is not enabled yet.
You can enable it by "echo 4 > /proc/pid/clear_refs."
