  "message": "virtio: indirect ring entries (VIRTIO_RING_F_INDIRECT_DESC)\n\nAdd a new feature flag for indirect ring entries. These are ring\nentries which point to a table of buffer descriptors.\n\nThe idea here is to increase the ring capacity by allowing a larger\neffective ring size whereby the ring size dictates the number of\nrequests that may be outstanding, rather than the size of those\nrequests.\n\nThis should be most effective in the case of block I/O where we can\npotentially benefit by concurrently dispatching a large number of\nlarge requests. Even in the simple case of single segment block\nrequests, this results in a threefold increase in ring capacity.\n\nSigned-off-by: Mark McLoughlin \u003cmarkmc@redhat.com\u003e\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\n",
