From 30a2d8328d8ac1bb0a6bf73f4f4cf03f4f5977cc Mon Sep 17 00:00:00 2001 From: David Vernet Date: Tue, 28 Feb 2023 09:28:45 -0600 Subject: bpf: Fix bpf_cgroup_from_id() doxygen header In commit 332ea1f697be ("bpf: Add bpf_cgroup_from_id() kfunc"), a new bpf_cgroup_from_id() kfunc was added which allows a BPF program to lookup and acquire a reference to a cgroup from a cgroup id. The commit's doxygen comment seems to have copy-pasted fields, which causes BPF kfunc helper documentation to fail to render: /helpers.c:2114: warning: Excess function parameter 'cgrp'... /helpers.c:2114: warning: Excess function parameter 'level'... /helpers.c:2114: warning: Excess function parameter 'level'... This patch fixes the doxygen header.
