From 7c7f2f2bc9a63f9605a16eabac59fc655dfe7c9a Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Mon, 17 Nov 2014 10:41:57 -0700 Subject: blk-mq: add blk_mq_free_hctx_request() It's silly to use blk_mq_free_request() which in turn maps the request to the hardware queue, for places where we already know what the hardware queue is. This saves us an extra mapping of a hardware queue on request completion, if the caller knows this information already.
