Subject: [PATCH for vm-scalability] usemem: Output a message after punch holes done

From: Hui Zhu <[email protected]>

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.
