Posted by Vladimir Sementsov-Ogievskiy 8 months, 1 week ago

v2: - now, based on master
    - CBW permissions a bit reworked
    - clamp down length to discard (thanks to Fiona)
    - use modern vm.cmd() in test instead of vm.qmp()

Vladimir Sementsov-Ogievskiy (4):
  block/copy-before-write: fix permission
  block/copy-before-write: create block_copy bitmap in filter node
  qapi: blockdev-backup: add discard-source parameter
  iotests: add backup-discard-source
