Hi All,

Let us assume that multiple processes are waiting on wait_event()\ wait_event_interruptible()\ wait_event_interruptible_timeout(), which process gets woken up on calling wake_up()??

I presume wake_up() picks one process, but is there any algorithm to pick which process?

try it and see! :)
