Hi !!
Just a small query,
When wait_event_interruptible is used, does it needs to be awakened by the wake_up_interruptible() call or it comes out of sleep when the condition gets true.
Although LDD talks about it, its example have got me confused, the example on pg 150 of scullpipe, it uses the wait_event_interruptible but also calls
the wake_up_interruptible to wake up readers/writers.
TIA Regards Ketan
