Subject: qcow2: Remove BDRVQcow2State.cluster_sectors
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=433e8e3b22021027ab8bc27f6fefa132fb33bfed;p=qmiga%2Fqemu.git

qcow2: Remove BDRVQcow2State.cluster_sectors

The last user of this field disappeared when we replace the
sector-based bdrv_write() with the byte-based bdrv_pwrite().
