[Libguestfs] [RFC libnbd PATCH 0/4] Add CMD_FLAG_DF support

[Eric Blake]

RFC because this is an API break, but we haven't declared stable API
yet. If we like it, I'm working on using libnbd to implement the
nbdkit-nbd plugin; knowing whether it is API version 0.1 or 0.2 will
be useful. I also dabbled with allowing optional parameters in python,
although my OCaml is weak enough that there may be cleaner ways to
approach that.

Eric Blake (4):
  api: Add flags parameter to pread, trim, cache, disconnect
  api: Rearrange flags argument to block_status
  python: Let flags parameter be optional
  api: Add DF flag support for pread
