[PATCH][next] net/mlx5: Use fallthrough pseudo-keyword
From: "Gustavo A. R. Silva" <gustavoars@kernel.org>
Date: 2020-07-27 17:58:09
Also in:
bpf, linux-rdma, lkml
Subsystem:
mellanox ethernet driver (mlx5e), mellanox ethernet innova drivers, mellanox mlx5 core vpi driver, networking drivers, the rest, xdp (express data path) · Maintainers:
Saeed Mahameed, Tariq Toukan, Mark Bloch, Leon Romanovsky, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds, Alexei Starovoitov, Daniel Borkmann, David S. Miller, Jesper Dangaard Brouer, John Fastabend
Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.
