From e999dbc254044e8d2a5818d92d205f65bae28f37 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sun, 19 Oct 2014 17:13:57 +0200 Subject: Revert "block: all blk-mq requests are tagged" This reverts commit fb3ccb5da71273e7f0d50b50bc879e50cedd60e7. SCSI-2/SPI actually needs the tagged/untagged flag in the request to work properly. Revert this patch and add a follow on to set it in the right place.
