[Qemu-devel] [PATCH 1/2] block/qcow2.c: rename qcow_ functions to qcow2_

[Qemu-devel] [PATCH 1/2] block/qcow2.c: rename qcow_ functions to qcow2_ |
|
Date: |
Thu, 16 Dec 2010 17:05:31 +0100 |
From: Jes Sorensen <address@hidden>
It doesn't really make sense for functions in qcow2.c to be named
qcow_ so convert the names to match correctly.
