[PATCH v2 0/6] NBD spec changes for 64-bit extensions

[Eric Blake]

This is the NBD spec series; there are matching qemu and libnbd
patches that implement the changes in this series.  I'm happy to drop
the RFC patches from all three, but wanted the conversation on whether
it makes sense to have 64-bit holes during NBD_CMD_READ first (it
would make more sense if we had a way for a client and server to agree
on a single-transaction buffer limit much larger than 32M).

Eric Blake (6):
  spec: Recommend cap on NBD_REPLY_TYPE_BLOCK_STATUS length
  spec: Tweak description of maximum block size
  spec: Add NBD_OPT_EXTENDED_HEADERS
  spec: Allow 64-bit block status results
  spec: Introduce NBD_FLAG_BLOCK_STATUS_PAYLOAD
  RFC: spec: Introduce NBD_REPLY_TYPE_OFFSET_HOLE_EXT
