.SH NAME
finish_task_switch \- clean up after a task-switch
.SH SYNOPSIS
"SYNOPSIS"
.sp
\fB
.sp
void finish_task_switch  (runqueue_t * \fIrq\fB, task_t * \fIprev\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIrq\fB\fR
-- undescribed --
.TP
\fB\fIprev\fB\fR
the thread we just switched away from.
.SH "DESCRIPTION"
.PP
finish_task_switch must be called after the context switch, paired
with a prepare_task_switch call before the context switch.
finish_task_switch will reconcile locking set up by prepare_task_switch,
and do any other architecture-specific cleanup actions.
.PP
Note that we may have delayed dropping an mm in \fBcontext_switch\fR\&. If
so, we finish that here outside of the runqueue lock.  (Doing it
with the lock held can cause deadlocks; see \fBschedule\fR for
details.)
