Subject: qemu-img bench: Fix uninitialised writethrough mode
X-Git-Tag: v2.7.0-rc0~117^2~19
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=604e86136266d104210a74be4c82643300c74e69;p=thirdparty%2Fqemu.git

qemu-img bench: Fix uninitialised writethrough mode

If no -t option is specified, bool writethrough stayed uninitialised.
Initialise it as false, which makes cache=writeback the default cache
mode.
