Possibly this was done by your mail client or mail server. In any case the result is that the patch doesn't apply. And unfortunately that breaks our processes. Also, assuming that as this patch is a not a bug fix, it is targeted at the "net-next", as opposed to "net", tree. This should be noted in the subject. Subject: [PATCH net-next v2] ... Looking at the git history of eswitch.c, I think that a better prefix for the patch is "mlx5/core: E-Switch, " Subject: [PATCH net-next v2] mlx5/core: E-Switch, ... > --- > drivers/net/ethernet/mellanox/mlx5/core/eswitch.c | 1 - > 1 file changed, 1 deletion(-) > > diff --git a/drivers/net/ethernet/mellanox/mlx5/core/eswitch.c b/drivers/net/ethernet/mellanox/mlx5/core/eswitch.c > index 31956cd9d..ae0939488 100644 > --- a/drivers/net/ethernet/mellanox/mlx5/core/eswitch.c > +++ b/drivers/net/ethernet/mellanox/mlx5/core/eswitch.c > @@ -805,7 +805,6 @@ static int mlx5_esw_vport_caps_get(struct mlx5_eswitch *esw, struct mlx5_vport * > hca_caps = MLX5_ADDR_OF(query_hca_cap_out, query_ctx, capability); > vport->info.roce_enabled = MLX5_GET(cmd_hca_cap, hca_caps, roce); > > - memset(query_ctx, 0, query_out_sz); I'm not saying this change is wrong. But I am saying that it's not immediately obvious to me why it is correct. And in any case, I think the patch description needs to describe why it is correct. Likewise, "Remove unneeded code" seems rather terse. Also, FWIIW, I don't see this when using coccicheck. But perhaps that's just me. I'm using: make C=2 CHECK=scripts/coccicheck drivers/net/ethernet/mellanox/mlx5/core/eswitch.o > err = mlx5_vport_get_other_func_cap(esw->dev, vport->vport, query_ctx, > MLX5_CAP_GENERAL_2); > if (err) Please consider waiting for further review, and as appropriate, addressing the problems above and reposting your patch.
