backwards compability of systemtap
HI there,
It looks array syntax like "foobar["string",1]" is not supported
in stap version 0.5.4 which comes with redhat 4 update 3. But it is
definitely supported in stap Version 0.5.8 of redhat 4 update 4.
I am wondering if there is a way to run the compiled the module/C code
of version 0.5.8 on redhat 4 update 3. If yes, then it means I can
use the most recent features of systemtap to old version of redhat
releases.
When I try this, I got the following message from /var/log/messages:
Mar 12 09:51:19 perf8 kernel: stap_7948: disagrees about version of symbol
register_kprobe
Mar 12 09:51:19 perf8 kernel: stap_7948: Unknown symbol register_kprobe
Any comments?
Thanks,
