[Nbd] [PATCH v4 0/2] block size extension

[Eric Blake <eblake@...696...>]

In v4:

patch 1:
Drop NBD_REP_EXPORT; a list of NBD_REP_INFO is sufficient
Make it clear that NBD_REP_INFO followed by NBD_REP_ERR_* is okay
Wording adjustments based on review

patch 2:
stronger focus on default minimum block size of 1
allow servers to accept clients even when NBD_OPT_BLOCK_SIZE not
 used, or NBD_OPT_EXPORT_NAME used
drop restriction against length of 0
wording adjustments based on review

Eric Blake (2):
  doc: Use sequence of replies for NBD_OPT_INFO/GO
  doc: Add details on block sizes
