From 5b91704469c0f801e0219f26458356872c4145ab Mon Sep 17 00:00:00 2001 From: Wenchao Xia Date: Sat, 25 May 2013 11:09:45 +0800 Subject: block: dump snapshot and image info to specified output bdrv_snapshot_dump() and bdrv_image_info_dump() do not dump to a buffer now, some internal buffers are still used for format control, which have no chance to be truncated. As a result, these two functions have no more issue of truncation, and they can be used by both qemu and qemu-img with correct parameter specified.
