How would you implement such a method in userspace? kill() doesn't take any parameters but the pid of the process you want to send a signal to, and the signal to send. This would require a new system call, and be quite a bit of work. If you can solve this with an ebpf program, I strongly suggest you do that instead. -- Steve _______________________________________________ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
