[PATCH] udevd: throttle the forking of processes
If the system reaches a defined limit of processes in running state, udevd starts to count its own processes in running state from its session (all forked hotplug child processes, subprocesses and callouts) and throttles further process forking if the limit is reached. This should help setups with hundreds of events emitted hotplug events in parallel with hundreds of processes in "R" state. which makes the machine unresponsible. I placed a 100% cpu time consuming program in /etc/hotplug.d/ which runs for 5 seconds. With this patch I can load "scsi_debug add_host=100" without any major problem. Without the patch the box is completly unresponsible for many minutes.
