Subject: [PATCH bpf-next 2/4] bpf: selftests: Add sk_state to bpf_tcp_helpers.h
Date: Wed, 4 Aug 2021 22:01:31 -0700	[thread overview]
Message-ID: <20210805050131.1350420-1-kafai@fb.com> (raw)
In-Reply-To: <20210805050119.1349009-1-kafai@fb.com>

Add sk_state define to bpf_tcp_helpers.h.  Rename the existing
global variable "sk_state" in the kfunc_call test to "sk_state_res".
