Subject: [PATCH for vm-scalability] usemem: Output a message after punch holes done
Date: Wed, 14 Apr 2021 10:44:36 +0800 [thread overview]
Message-ID: <20210414024436.30128-1-teawater@gmail.com> (raw)
From: Hui Zhu <teawater@antfin.com>
When I use punch holes to setup a test page fragmentation environment, I
didn't know when the punch holes done. I can only get this information
through top or something else.
This commit add code to output a message after punch holes done to
handle this issue.
