From 2ecb204d07ac8debe3893c362415919bc78bebd6 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 3 Nov 2014 14:09:02 +0100 Subject: scsi: always assign block layer tags if enabled Allow a driver to ask for block layer tags by setting .use_blk_tags in the host template, in which case it will always see a valid value in request->tag, similar to the behavior when using blk-mq. This means even SCSI "untagged" commands will now have a tag, which is especially useful when using a host-wide tag map.
