36 There are currently two types of probes: kprobes, and kretprobes
37 (also called return probes). A kprobe can be inserted on virtually
43 one or more probes, and the exit function unregisters them. A
48 There are also ``register_/unregister_*probes()`` functions for batch
49 registration/unregistration of a group of ``*probes``. These functions

54 probes work and how jump optimization works. They explain certain

350 function for each type of probe. The API also includes "register_*probes"
351 and "unregister_*probes" functions for (un)registering arrays of probes.
470 register_*probes
479 Registers each of the num probes in the specified array. If any
480 error occurs during registration, all probes in the array, up to
481 the bad probe, are safely unregistered before the register_*probes
492 unregister_*probes
501 Removes each of the num probes in the specified array at once.
505 If the functions find some incorrect probes (ex. unregistered
506 probes) in the specified array, they clear the addr field of those
507 incorrect probes. However, other probes in the array are
