Thanks for the issue (and feedback)!

Could you provide the following?

  • Which kernel (uname -a)
  • Params for pwru
  • The first log lines before Listening for events

from pwru.

Why not attach/detach kprobes concurrently?

It seems a little better to attach/detach kprobes concurrently.

Cool!

I haven't tested, but it looks like detach is still an order of magnitude (p/s) slower? (This is not significant for my usecase.)

I think we could detach in batches too.

It does detach in batches: DetachKprobes()
