[root@zoo ~]# perf probe -F do_f* do_fb_ioctl do_fbcon_takeover do_file_open_root do_filp_open do_flush_tlb_all do_free_callbacks do_free_init do_fsync do_futex [root@zoo ~]# perf probe -F do_fo* no symbols found in [kernel.kallsyms], maybe install a debug package? Failed to load symbols in kernel [root@zoo ~]# I.e. it _finds_ the symbol table, its just that the globbing failed, the message should be improved, otherwise the user would start looking why the debuginfo, that _is_ in place, is not being enough, I did :-) - Arnaldo
