Subject: vmscan: tracing: Correct units in post-processing script
From: Mel Gorman <mel@csn.ul.ie>

The post-processing script is reporting the wrong units. Correct it.  This
patch updates vmscan-tracing-add-trace-event-when-a-page-is-written.patch
to include that information. The patches can be merged together.
