Subject[RFC PATCH 0/2] tracing - signal tracer, support multiple pids in set_pid_ftrace
Date
I was debugging some ptrace applications and got to the idea of 
tracing signals - signal tracer. There's probably possibility to
trace more info than just signal delivery info (like ignored
signals deliveries, queue status...).

While doing this I realized it might be worth to have ability to trace
more independent processes via set_pid_ftrace file.

Althought I'm sending this as RFC, attached patches work for me.
I'm open to any suggestions/comments/ideas.

1/2 - signal trace
2/2 - multiple pids support for set_pid_ftrace file

thanks,
jirka
