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.
Return
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.
