Why do you need the enum kmemtrace_type_id type_id exactly ? Can you
remove this parameter by adding more specific tracepoints ?

You'll probably want to give "cachep" as parameter and do the
slab_buffer_size(cachep) within the probe to remove unneeded code from
the caller site.

Same here for order.

Why do you need to pass -1 ? Can you have a more specific tracepoint
instead ?

Pass s as parameter and do the s->size dereference within the probe.

The same applies to many other caller sites below.
