Subject: qcow2: Replace bdrv_write() with bdrv_pwrite()
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=e3b4257d032dede8ffcfe868ffd74bb584842f62;p=qmiga%2Fqemu.git

qcow2: Replace bdrv_write() with bdrv_pwrite()

There's only one bdrv_write() call left in the qcow2 code, and it can
be trivially replaced with the byte-based bdrv_pwrite().
