[Qemu-block] [PATCH for-4.0 0/2] NBD block status failures

Subject: [Qemu-block] [PATCH for-4.0 0/2] NBD block status failures
Date: Sat, 23 Mar 2019 16:26:37 -0500

Rich pointed out some fishy corner-case behavior of qemu in dealing
with a non-compliant NBD server on NBD_CMD_BLOCK_STATUS. Fix a real
bug in qemu-img, as well as teaching NBD to be a bit more tolerant of
buggy servers for more interoperability (be strict in what you
produce, but loose in what you accept).

Eric Blake (2):
  qemu-img: Report bdrv_block_status failures
  nbd: Tolerate some server non-compliance in NBD_CMD_BLOCK_STATUS
