[Qemu-devel] [PATCH 00/25] nbd asynchronous operation

[Paolo Bonzini <pbonzini@redhat.com>]

Here is my NBD asynchronous operation series, including asynchronous
server.

Patches 1-5 add asynchronous operation to the client.

Patches 6-9 add new features for flush/FUA and discard (trim).

Patches 10-25 add asynchronous operation to the server.

Chunyan Liu (1):
  Update ioctl order in nbd_init() to detect EBUSY
