Unable to opendir /sys/bus/event_source/devices : No such file or directory

Wasn't aware of this message before - and got it now when running trinity within a 32 bit user-mode-linux.

Is that directory helpful for trinity ?

It is used when coming up with possible events for the perf_event_open() syscall.

It's not fatal if the directory doesn't exist.

I should probably remove the error message (or make it only show up at high verbosity levels?).

A patch that removes the message is included below.

-		fprintf(stderr,"Unable to opendir "

-			strerror(errno));
 		return -1;
 	}
 

less verbose at least, otherwise it is just irritating

thx
