Re: [nbdkit PATCH v2 13/13] RFC: plugins: Add callbacks for FUA semantics
Our cbdkit was branched from 1.1.12 with some patches from 1.1.13 added as
well. The project has morphed significantly enough that a direct diff or
merging between the two would not be feasible. Even the structure of the
project directory and build has been changed to be in line with our other
internal projec...

Thanks for the other email, I thought it was very interesting and I'm
glad that people are looking at the performance of nbdkit seriously.

Re: [nbdkit PATCH v2 13/13] RFC: plugins: Add callbacks for FUA semantics
Hi,
We've been using a modified nbdkit (ours is cbdkit internally) for about
half a year now and since you guys appear to be working on a next version
of the API I wanted to go over some of the limitations we hit with nbdkit
that we think others may also hit for consideration into the batch of
changes you are making to the api.

breaking things into smaller stages that piece together and possible
with fewer threads.

[nbdkit PATCH v2 00/13] Add filters + FUA support to nbdkit
A combination of the work that both Rich and I have been doing
lately, where filters use only the new API with flags on every
command that the client can send over the wire (we can then
add support for more flags in nbdkit without having to add new
callbacks, as NBD adds more flags upstream).

protocol: Split flags from cmd field in requests
backend: Pass flags argument through
