This series is posted alongside a spec change to NBD, and
interoperable with changes posted to qemu-nbd/qemu-storage-daemon.
The RFC patch at the end is optional; ineroperability with qemu works
only when either both projects omit the RFC patch, or when both
projects include it (if only one of the two RFC projects include it,
the protocol is incompatible between the two, but at least client and
server gracefully detect the bug rather than SEGV'ing).
Eric Blake (23):
block_status: Refactor array storage
internal: Refactor layout of replies in sbuf
protocol: Add definitions for extended headers
states: Prepare to send 64-bit requests
states: Prepare to receive 64-bit replies
states: Break deadlock if server goofs on extended replies
generator: Add struct nbd_extent in prep for 64-bit extents
block_status: Track 64-bit extents internally
block_status: Accept 64-bit extents during block status
api: Add [aio_]nbd_block_status_64
api: Add several functions for controlling extended headers
copy: Update nbdcopy to use 64-bit block status
dump: Update nbddump to use 64-bit block status
info: Expose extended-headers support through nbdinfo
info: Update nbdinfo --map to use 64-bit block status
examples: Update copy-libev to use 64-bit block status
ocaml: Add example for 64-bit extents
generator: Actually request extended headers
api: Add nbd_[aio_]opt_extended_headers()
interop: Add test of 64-bit block status
api: Add nbd_can_block_status_payload()
api: Add nbd_[aio_]block_status_filter()
RFC: pread: Accept 64-bit holes
