.SH "NAME"
mod_delayed_work_on \- modify delay of or queue a delayed work on specific CPU
.SH "SYNOPSIS"
.HP \w'bool\ mod_delayed_work_on('u
.BI "bool mod_delayed_work_on(int\ " "cpu" ", struct\ workqueue_struct\ *\ " "wq" ", struct\ delayed_work\ *\ " "dwork" ", unsigned\ long\ " "delay" ");"
.SH "ARGUMENTS"
.PP
\fIcpu\fR
.RS 4
CPU number to execute work on
.RE
.PP
\fIwq\fR
.RS 4
workqueue to use
.RE
.PP
\fIdwork\fR
.RS 4
work to queue
.RE
.PP
\fIdelay\fR
.RS 4
number of jiffies to wait before queueing
.RE
.SH "DESCRIPTION"
.PP
If
\fIdwork\fR
is idle, equivalent to
\fBqueue_delayed_work_on\fR; otherwise, modify
\fIdwork\fR\*(Aqs timer so that it expires after
\fIdelay\fR\&. If
\fIdelay\fR
is zero,
\fIwork\fR
is guaranteed to be scheduled immediately regardless of its current state\&.
.SH "RETURN"
.PP
\fBfalse\fR
if
\fIdwork\fR
was idle and queued,
\fBtrue\fR
if
\fIdwork\fR
was pending and its timer was modified\&.
.PP
This function is safe to call from any context including IRQ handler\&. See
\fBtry_to_grab_pending\fR
for details\&.
