Hi,
I'm trying to monitor changes to mm->nr_ptes. I'd like to probe
__pte_alloc in mm/memory.c but systemtap cannot see it. Why is that?
Do I have to identify and probe all functions where a change is made
to mm->nr_ptes or can I watch for changes to mm->nr_ptes? I looked at
the watchpoint systemtap examples but they seem to apply only to
global symbols.
Thanks.
