In commit332ea1f697("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: <snip>/helpers.c:2114: warning: Excess function parameter 'cgrp'... <snip>/helpers.c:2114: warning: Excess function parameter 'level'... <snip> <snip>/helpers.c:2114: warning: Excess function parameter 'level'... This patch fixes the doxygen header.
