hi --
about systemtap script
when I use this kind probe "module(MPATTERN).statement(PATTERN)"
allway write PATTERN like:*@globalvar/globalvar.c:59
the line number is a problem. I want this kind probe can support
PATTERN like this :
globalvar.c:
15:void globalvar_read()
16:{
17: int a;
18 int b;
....;
30 a += 100;
31 return;
32}
if I want attch line 30, I want to use functionname add offset in function
can systemtap support this PATTERN?
or anyway can support like this?

This is described in the stapprobes man page.
Try .statement("globalvar_read@globalvar/globalvar.c+15").
Thanks,
Roland
