[Qemu-devel] [PATCH 0/3] nbd: Use common read/write-all qio functions

[Eric Blake <eblake@redhat.com>]

Now that Daniel just added convenience qio channel looping functions,
we might as well use it in NBD instead of open-coding our own.  In
doing so, fix a couple of short-falls noticed in the qio code.

If Dan is happy with this, I can take the series through the NBD queue.

[The diffstat is slightly misleading - it's a net reduction in lines
of code, but the added comments hide that fact]

Eric Blake (3):
  io: Yield rather than wait when already in coroutine
  io: Add new qio_channel_read{,v}_all_eof functions
  nbd: Use new qio_channel_*_all() functions
