Cover letter [RFC PATCH 0/2] uprobes: register/unregister can race with fork
Hello.
Well. The very fact this series adds the new locking primitive probably means we should try to find another fix. And yes, it is possible to fix this differently, afaics. But this will need more complications, I think.
So please review. As for 1/2:
- I really hope paulmck/peterz will tell me if it is correct or not
- The naming sucks, and I agree with any suggestions
- Probably this code should be compiled only if CONFIG_UPRPOBES
Oleg.
