[PATCH 00/14] qemu patches for NBD_OPT_EXTENDED_HEADERS

[Eric Blake]

Available at https://repo.or.cz/qemu/ericb.git/shortlog/refs/tags/exthdr-v1

Patch 14 is optional; I'm including it now because I tested with it,
but I'm also okay with dropping it based on RFC discussion.

Eric Blake (14):
  nbd/server: Minor cleanups
  qemu-io: Utilize 64-bit status during map
  qemu-io: Allow larger write zeroes under no fallback
  nbd/client: Add safety check on chunk payload length
  nbd/server: Prepare for alternate-size headers
  nbd: Prepare for 64-bit requests
  nbd: Add types for extended headers
  nbd/server: Initial support for extended headers
  nbd/server: Support 64-bit block status
  nbd/client: Initial support for extended headers
  nbd/client: Accept 64-bit hole chunks
  nbd/client: Accept 64-bit block status chunks
  nbd/client: Request extended headers during negotiation
  do not apply: nbd/server: Send 64-bit hole chunk
