Subject: blockdev: do not default cache.no-flush to true
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=07ae07c96711f4b69c3e72a96996c25732544762;p=sdk%2Femulator%2Fqemu.git

blockdev: do not default cache.no-flush to true

That's why all my VMs were so fast lately. :)

This changed in 1.6.0 by mistake in patch 29c4e2b (blockdev: Split up
'cache' option, 2013-07-18).
