/*
QEMU 2.11 introduced the --shrink option for qemu-img resize to avoid accidentally shrinking images (commit 4ffca8904a3). However, for compatibility reasons, it was not enforced for raw images yet, but only a deprecation warning was printed. This warning has existed for long enough that we can now finally require --shrink for raw images, too, and error out if it's not given. Documentation already describes the state as it is after this patch. Signed-off-by: Kevin Wolf <kwolf@redhat.com> --- qemu-img.c | 17 +++-------------- 1 file changed, 3 insertions(+), 14 deletions(-)
