From: Jason Xing Date: Sat, 6 Apr 2024 14:46:13 +0000 (+0800) Subject: selftests/bpf: eliminate warning of get_cgroup_id_from_path() X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=bb761fcb821738e8d3b720e1460d3783db74c68a;p=linux.git selftests/bpf: eliminate warning of get_cgroup_id_from_path() The output goes like this if I make samples/bpf: ...warning: no previous prototype for ‘get_cgroup_id_from_path’... Make this function static could solve the warning problem since no one outside of the file calls it.
