Kprobes (Kernel dynamic probes) is a lightweight mechanism for kernel
modules to insert probes into a running kernel, without the need to modify
the underlying source.  The probe handlers can then be coded to log
relevent data at the probe point.  More information on kprobes can be found
at:

Jprobes (or jumper probes) is a small infrastructure to access function
arguments.  It can be used by defining a small stub with the same template
as the routine in kernel, within which the required parameters can be
logged.
