All clean cherry picks. Patch #1 is a small cleanup that allows Patch #2
to apply cleanly. Patch #3 improves the performance of Patch #2. All 3
patches were introduced in v5.2, so they've had plenty of "bake time"
together.


Yunsheng Lin (3):
  net: hns3: minor optimization for ring_space
  net: hns3: fix data race between ring->next_to_clean
  net: hns3: optimize the barrier using when cleaning TX BD
