[Bug runtime/6416] New: SystemTap should recognize and disble probes on __devinit/__devexit functions


stap on a simple script:

probe kernel.function("*@drivers/net/ibmveth.c")
{
   printf("%s\n", probefunc());
}

fails with the following error:

ERROR: probe kernel.function("ibmveth_probe@drivers/net/ibmveth.c:1103")
registration error (rc -22)
stapio:stp_main_loop:301 probe_start() returned -1
stapio:cleanup_and_exit:216 CLEANUP AND EXIT  closed=1

This is because ibmveth_probe is annotated __devinit and as such will be
discarded after device initialization. Similarly for __devexit functions also.

Like is currently done with __init and __exit section symbols, SystemTap must
recognize and not probe __devinit/__devexit section symbols too.
