commit 0d360d64
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4PKDW
CVE: NA

--------------------------------

I get the following error during compilation on my side:
kernel/trace/bpf_trace.c: In function 'bpf_do_trace_printk':
kernel/trace/bpf_trace.c:386:34: error: function 'bpf_do_trace_printk' can never be inlined because it uses variable argument lists
 static inline __printf(1, 0) int bpf_do_trace_printk(const char *fmt, ...)
                                  ^

Fixes: ac5a72ea ("bpf: Use dedicated bpf_trace_printk event instead of trace_printk()")
