File sheepdog-Consistently-set-bdrv_has_zero_.patch of Package qemu
From: Eric Blake <eblake@redhat.com> Date: Tue, 24 Mar 2020 12:42:33 -0500 Subject: sheepdog: Consistently set bdrv_has_zero_init_truncate MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Git-commit: ed049910637be991c88cc25c864115bc5b1e4dab block_int.h claims that .bdrv_has_zero_init must return 0 if .bdrv_has_zero_init_truncate does likewise; but this is violated if only the former callback is provided if .bdrv_co_truncate also exists. When adding the latter callback, it was mistakenly added to only one of the three possible sheepdog instantiations.
