Subject: [PATCH bpf-next 1/8] bpf: Add fsession to verbose log in check_get_func_ip()
Date: Tue, 24 Feb 2026 23:40:17 +0800 [thread overview]
Message-ID: <20260224154024.12504-2-leon.hwang@linux.dev> (raw)
In-Reply-To: <20260224154024.12504-1-leon.hwang@linux.dev>
Since bpf_get_func_ip() is supported for fsession intuitively, add
fsession to the verbose log in check_get_func_ip().
No functional change intended.
