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.

This will however increase the vmlinux size even when no tracing is
enabled. Why cannot we simply print the name of the shrinker
callbacks?

What mechanism do you have in mind for obtaining the name,
Michal?

Not sure whether tracing infrastructure allows printk like %ps. If not
then it doesn't sound too hard to add.
