From 17ded320706c6316376059cfbe9dccab32c62b42 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Wed, 7 Jan 2015 10:44:04 -0700 Subject: blk-mq: get rid of ->cmd_size in the hardware queue We store it in the tag set, we don't need it in the hardware queue. While removing cmd_size, place ->queue_num further down to avoid a hole on 64-bit archs. It's not used in any fast paths, so we can safely move it.
