Subject: [Qemu-devel] [PATCH 00/12] nbd improvements
Date: Thu,  8 Sep 2011 17:24:53 +0200	[thread overview]
Message-ID: <1315495505-28906-1-git-send-email-pbonzini@redhat.com> (raw)

I find nbd quite useful to test migration, but it is limited:
it can only do synchronous operation, it is not safe because it
does not support flush, and it has no discard either.  qemu-nbd
is also limited to 1MB requests, and the nbd block driver does
not take this into account.

Luckily, flush/FUA support is being worked out by upstream,
and discard can also be added with the same framework (patches
1 to 6).

Asynchronous support is also very similar to what sheepdog is
already doing (patches 7 to 12).

Paolo Bonzini (12):
  nbd: support feature negotiation
  nbd: sync API definitions with upstream
  nbd: support NBD_SET_FLAGS ioctl
  nbd: add support for NBD_CMD_FLUSH
  nbd: add support for NBD_CMD_FLAG_FUA
  nbd: support NBD_CMD_TRIM in the server
  sheepdog: add coroutine_fn markers
  add socket_set_block
  sheepdog: move coroutine send/recv function to generic code
  block: add bdrv_co_flush support
  nbd: switch to asynchronous operation
  nbd: split requests
