stap -e 'probe kernel.function("*") { log("."); }'
results in
ERROR: dwarf probe
kernel.function("exit_pfm_fs@arch/ia64/kernel/perfmon.c:1507")
registration failed, rc=1
Looks like on Ia64, stap is translating to functions which are in
__exit sections, as in the above failure case exit_pfm_fs() function
is prefixed with __exit and when the module is loaded the
kprobe registration fails as the functions in exit sections no longer
exist.
I am running the latest systemtap from the CVS, please let me
know if their is a workaround.
thanks,
