Jim,
Earlier kprobes used a spin_lock() to serialize kprobe execution and hence to
avoid deadlocks waiting for spin_lock(), kprobes section was introduced.
Also this kprobes section was useful to avoid probes on other routines which
caused system crash.
Now since we have RCU based implementation, we need to re-evaluate if actually
__kprobes section is required for all the routines used by kprobes. In such a
case mark only those routines where probes on them would be unsafe.
Thanks
Prasanna
