Subject: [PATCH 08/15] libata: add ATA_QCFLAG_IO
Date: Sun, 2 Apr 2006 18:51:53 +0900 [thread overview]
Message-ID: <1143971513867-git-send-email-htejun@gmail.com> (raw)
In-Reply-To: <11439715124131-git-send-email-htejun@gmail.com>
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.
