Re: [PATCH] api: Add a special type for the flags argument.
..., nbd.CMD_FLAG_FUA)
There's still the question of how to pass two flags at once; if I
understand your patch (and after confirming it with nbdsh), we have to
write:
h.zero (64*1024, 0, nbd.CMD_FLAG_FUA | nbd.CMD_FLAG_NO_HOLE)
[side note - requires a server that supports flush; to my surprise,
nbkdit 'null' does but 'memory' did not; I'll probably fix that]
I don't know if we want to somehow allow:
h.zero (64*1024, 0, nbd.CMD_FLAG_FUA, nbd.CMD_FLAG_NO_HOLE)
instead (two arguments, each with one flag, which the glue code then
combines into a single integer; compared to...

[nbdkit PATCH 1/3] server: Add internal support for NBDKIT_FLAG_FAST_ZERO
Qemu was able to demonstrate that knowing whether a zero operation is
fast is useful when copying from one image to another: there is a
choice between bulk pre-zeroing and then revisiting the data sections
(fewer transactions, but depends on the zeroing to be fast),
vs. visiting every portion of the disk only once (more transactions,
but no time lost to duplicated I/O due to slow zeroes). As

[libnbd PATCH v3 0/2] Implementing NBD_OPT_LIST
This is a subset of my v2 posting, but limited to just the
NBD_OPT_LIST handling. The biggest change since v2 is the addition of
added unit testing in all four language bindings (C, python, ocaml,
golang). The tests require nbdkit built from git on PATH, and may not
be entirely idiomatic, but I at least validated that they catch issues
(for example, adding an exit statement near the end of the

[PATCH nbdkit 0/9] Create libnbdkit.so
This creates libnbdkit.so as discussed in the following thread:

test-delay-shutdown.sh fails for unclear reasons.
This series starts by reverting "tests: Don't strand hung nbdkit
processes" which is because several other tests fail randomly unless I
revert this patch. I didn't investigate this yet so it
