Subject: [PATCH bpf-next v3 23/24] selftests/bpf: Add __contains macro to bpf_experimental.h
Date: Thu, 3 Nov 2022 01:56:57 +0530 [thread overview]
Message-ID: <20221102202658.963008-24-memxor@gmail.com> (raw)
In-Reply-To: <20221102202658.963008-1-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.

/* Description
* Allocates a local kptr of type represented by 'local_type_id' in program
* BTF. User may use the bpf_core_type_id_local macro to pass the type ID
