From b666da35d900c26cbea1caa465649e2e0afa406c Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 26 Oct 2007 15:53:59 +0900 Subject: [PATCH] libata: flush is an IO command ATA_QCFLAG_IO is used to mark commands which are used to perform regluar IO transfers via block layer. These commands are assumed to be valid and taken more seriously during error handling. Cache flush is used by regular IO path and necessary for data integrity. Mark it with ATA_QCFLAG_IO.
