Subject: [PATCH 1/3] Add a new field to struct shrinker
Date: Sat, 9 Jul 2016 04:43:31 -0400 [thread overview]
Message-ID: <85a9712f3853db5d9bc14810b287c23776235f01.1468051281.git.janani.rvchndrn@gmail.com> (raw)
In-Reply-To: <cover.1468051277.git.janani.rvchndrn@gmail.com>
Struct shrinker does not have a field to uniquely identify the shrinkers
it represents. It would be helpful to have a new field to hold names of
shrinkers. This information would be useful while analyzing their
behavior using tracepoints.
