Subject: [PATCH bpf-next v2 3/5] bpf: Mark bpf_refcount field as unique
Date: Sun, 19 Jul 2026 17:36:30 +0200 [thread overview]
Message-ID: <20260719153634.2908692-4-memxor@gmail.com> (raw)
In-Reply-To: <20260719153634.2908692-1-memxor@gmail.com>
BPF_REFCOUNT is not marked as a unique field, while it should be. Fix
this oversight.
Fixes: d54730b50bae ("bpf: Introduce opaque bpf_refcount struct and add btf_record plumbing")
