Hi Masami,
Could you please improve this?
[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 :-)
