Subject: perf probe: Misleading error message using function globbing
Date: Fri, 4 Sep 2015 12:41:55 -0300	[thread overview]
Message-ID: <20150904154155.GC3284@kernel.org> (raw)

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 :-)

- Arnaldo
