419 \subsubsection{\label{sec:request-types}Request types}
520 \item[C -- complete] A previously issued request has been completed.
521 The output will detail the sector and size of that request, as well
524 \item[D -- issued] A request that previously resided on the block layer
527 \item[I -- inserted] A request is being sent to the io scheduler for
529 request is fully formed at this time.
544 \item[M -- back merge] A previously inserted request exists that ends
551 \item[G -- get request] To send any type of request to a block device,
552 a \emph{struct request} container must be allocated first.
554 \item[S -- sleep] No available request structures were available, so
561 \item[U -- unplug] Some request data already queued in the device,
