[Qemu-devel] [PATCH] Remove osdep.c/qemu-img code duplication

[Kevin Wolf <kwolf@suse.de>]

[-- Attachment #1: Type: text/plain, Size: 382 bytes --]

There are few helper functions (e.g. qemu_malloc) in osdep.c which are
not OS dependent at all. Even the first CVS commit comment for osdep.c
says "most functions are generic in fact". They are duplicated in
qemu-img because osdep.c isn't used there.

This patch moves those functions to cutils.c and removes the duplicates
from qemu-img.

Signed-off-by: Kevin Wolf <kwolf@suse.de>
