------------------------------------------------------
Subject: schedule_work() documentation improvements
From: Bart Van Assche <bart.vanassche@xxxxxxxxx>
Two important aspects of the schedule_work() function are not yet documented:
- that it is allowed to pass a struct work_struct * to this function that
is already on the kernel-global workqueue;
- the meaning of its return value.
The patch below documents both aspects.
