wait_event_* and wake_up_*

2014-07-22 Thread Pranith Kumar 
Hello,

Could someone point me to good documentation about the wait_event_*
and wake_up_* event family APIs?

I tried searching and nothing concrete shows up.

In particular:

When do we use wake_up_interruptible()? Does wake_up(wq) wake up all
the threads which are waiting on that work queue? Is the waking up of
threads sequential?

That should suffice for now I guess :)
