MOD_DELAYED_WORK_ON(9) Driver Basics MOD_DELAYED_WORK_ON(9)

NAME

mod_delayed_work_on - modify delay of or queue a delayed work on specific CPU

SYNOPSIS

bool mod_delayed_work_on(int cpu, struct workqueue_struct * wq, struct delayed_work * dwork, unsigned long delay);

ARGUMENTS

cpu

CPU number to execute work on

wq

workqueue to use

dwork

work to queue

delay

number of jiffies to wait before queueing

DESCRIPTION

If dwork is idle, equivalent to queue_delayed_work_on; otherwise, modify dwork's timer so that it expires after delay. If delay is zero, work is guaranteed to be scheduled immediately regardless of its current state.

Returns false if dwork was idle and queued, true if dwork was pending and its timer was modified.

This function is safe to call from any context including IRQ handler. See try_to_grab_pending for details.
