Revision 1a50cf9a67ff2241c2949d30bc11c8dd4280eef8 authored by Maxim Mikityanskiy on 22 October 2020, 09:49:51 UTC, committed by Saeed Mahameed on 05 November 2020, 20:17:06 UTC
rq->xdp_prog is RCU-protected and should be accessed only with
rcu_access_pointer for the NULL check in mlx5e_poll_rx_cq.
rq->xdp_prog may change on the fly only from one non-NULL value to
another non-NULL value, so the checks in mlx5e_xdp_handle and
mlx5e_poll_rx_cq will have the same result during one NAPI cycle,
meaning that no additional synchronization is needed.
