[Qemu-devel] [PATCH 0/4] qemu-img: conditionally discard target on convert

[Peter Lieven <pl@kamp.de>]

this adds the proposed solution to add a generic mechanism to zeroize
a target in qemu-img if it has discard_zeroes but has_zero_init is 0.

Peter Lieven (4):
  block: add discard_zeroes and max_unmap to BlockDriverInfo
  iscsi: add .bdrv_get_info
  block/raw: add .bdrv_get_info
  qemu-img: conditionally discard target on convert
