.SH "DESCRIPTION"
.PP
The block layer may perform asynchronous callback activity
on a queue, such as calling the unplug function after a timeout.
A block device may call blk_sync_queue to ensure that any
such activity is cancelled, thus allowing it to release resources
the the callbacks might use. The caller must already have made sure
that its ->make_request_fn will not re-add plugging prior to calling
this function.
