[PATCH 1/3] Add a new field to struct shrinker

Show all headers | View raw

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.
