From 82ed4db499b8598f16f8871261bff088d6b0597f Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 27 Jan 2017 09:46:29 +0100 Subject: block: split scsi_request out of struct request And require all drivers that want to support BLOCK_PC to allocate it as the first thing of their private data. To support this the legacy IDE and BSG code is switched to set cmd_size on their queues to let the block layer allocate the additional space.
