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?

-- Thanks, Sekhar Sorry to spoil the fun here. But check out what the queue data structure is all about. 'wait_queue' :)

Thank you Bharath
