[Qemu-devel] [PATCH for 2.6 1/1] iotests: fix the broken 026.nocache output

["Denis V. Lunev" <den@openvz.org>]

From: Pavel Butsykin <pbutsykin@virtuozzo.com>

This patch fixes longstanding issue with 026 iotest. Unfortunately,
this test contains 2 versions of the correct output, one for cached
writes and one for non-cached ones. People tends to fix only one
version of output of the test and thus noncached version becomes
broken. Unfortunately, it is default in tests/check-block.sh

The following problematic commits were made:
    commit 3b5e14c76a6bb142bf250ddf99e24a0ac8c7bc12
