From 2719736779da2c7fbb17d3de16c817b429bfeb9c Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sun, 2 Apr 2006 18:51:53 +0900 Subject: [PATCH] [PATCH] libata: add ATA_QCFLAG_IO Add a new qc flag ATA_QCFLAG_IO. This flag gets set for normal IO commands originating from SCSI midlayer. This information will be used by EH to determine transfer speed reconfiguration.
