[PATCH v2 0/2] virtio: clean up of virtqueue_split_read_next_desc()

Posted by Ilya Maximets 7 months, 1 week ago

Version 2:
  - Converted into a patch set adding a new patch that removes the
    'next' argument.  [Stefan]
  - Completely removing the barrier instead of changing into compiler
    barrier.  [Stefan]


Ilya Maximets (2):
  virtio: remove unnecessary thread fence while reading next descriptor
  virtio: remove unused next argument from
    virtqueue_split_read_next_desc()
