.SH NAME
blk_queue_start_tag \- find a free tag and assign it
.SH SYNOPSIS
.sp
\fB
.sp
int blk_queue_start_tag  (request_queue_t * \fIq\fB, struct request * \fIrq\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIq\fB\fR
the request queue for the device
.TP
\fB\fIrq\fB\fR
the block request that needs tagging
.SH "DESCRIPTION"
.PP
This can either be used as a stand-alone helper, or possibly be
assigned as the queue &prep_rq_fn (in which case &struct request
automagically gets a tag assigned). Note that this function
assumes that any type of request can be queued! if this is not
true for your device, you must check the request type before
calling this function.  The request will also be removed from
the request queue, so it's the drivers responsibility to readd
it if it should need to be restarted for some reason.
.SH "NOTES"
.PP
queue lock must be held.
