Subject: [PATCH bpf-next v6 22/26] selftests/bpf: Add __contains macro to bpf_experimental.h
Date: Sat, 12 Nov 2022 01:02:20 +0530 [thread overview]
Message-ID: <20221111193224.876706-23-memxor@gmail.com> (raw)
In-Reply-To: <20221111193224.876706-1-memxor@gmail.com>
Add user facing __contains macro which provides a convenient wrapper
over the verbose kernel specific BTF declaration tag required to
annotate BPF list head structs in user types.
