[dpdk-dev] [PATCH RFC 0/4] Thread safe rte_vhost_enqueue_burst().

[Ilya Maximets <i.maximets@samsung.com>]

Implementation of rte_vhost_enqueue_burst() based on lockless ring-buffer
algorithm and contains almost all to be thread-safe, but it's not.

This set adds required changes.

First patch in set is a standalone patch that fixes many times discussed
issue with barriers on different architectures.

Second and third adds fixes to make rte_vhost_enqueue_burst thread safe.
Last is a documentation fix.

Ilya Maximets (4):
  vhost: use SMP barriers instead of compiler ones.
  vhost: make buf vector for scatter RX local.
  vhost: avoid reordering of used->idx and last_used_idx updating.
  doc: add note about rte_vhost_enqueue_burst thread safety.
