It should be only used within the vhost ops\nwhich already holds the lock. Like vring state changes or device is\ndestroyed. Compared with rte_vhost_async_get_inflight(), this is a\nlock free version.\n\nRFC v1->v1:\n* refine the doc and commit log\n\nXuan Ding (2):\n vhost: add unsafe API to check inflight packets\n examples/vhost: use API to check inflight packets\n\n doc/guides/prog_guide/vhost_lib.rst | 6 ++++++\n doc/guides/rel_notes/release_22_07.rst | 4 ++++\n examples/vhost/main.c | 28 ++++++++++++++------------\n examples/vhost/main.h | 1 -\n lib/vhost/rte_vhost_async.h | 17 ++++++++++++++++\n lib/vhost/version.map | 4 ++++\n lib/vhost/vhost.c | 26 ++++++++++++++++++++++++\n 7 files changed, 72 insertions(+), 14 deletions(-)", "diff": null, "prefixes": [ "v1", "0/2" ] }
