From 9ad93ba528bf5555a96ef64b7ec1af398277ad52 Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk Date: Mon, 10 Oct 2011 12:33:21 -0400 Subject: [PATCH] xen/blkback: Report VBD_WSECT (wr_sect) properly. commit 5c62cb48602dba95159c81ffeca179d3852e25be upstream. We did not increment the amount of sectors written to disk b/c we tested for the == WRITE which is incorrect - as the operations are more of WRITE_FLUSH, WRITE_ODIRECT. This patch fixes it by doing a & WRITE check.
