Date: Fri, 18 Dec 2020 10:50:31 -0800 From: Jonathan Lemon <jonathan.lemon@...il.com> To: <netdev@...r.kernel.org>, <ast@...nel.org>, <daniel@...earbox.net>, <yhs@...com>, <bpf@...r.kernel.org> CC: <kernel-team@...com> Subject: [PATCH 2/3 v4 bpf-next] bpf: Use thread_group_leader() From: Jonathan Lemon <bsd@...com> Instead of directly comparing task->tgid and task->pid, use the thread_group_leader() helper. This helps with readability, and there should be no functional change.
