Cross-project NBD extension proposal: NBD_INFO_INIT_STATE
I will be following up to this email with four separate threads each
addressed to the appropriate single list, with proposed changes to:
- the NBD protocol
- qemu: both server and client
- libnbd: client
- nbdkit: server
The feature in question adds a new optional NBD_INFO_ packet to the
NBD_OPT_GO portion of handshake, adding up to 16 bits of information
that the server can advertise to the
