29 There are currently three types of probes: kprobes, jprobes, and
30 kretprobes (also called return probes).  A kprobe can be inserted
38 one or more probes, and the exit function unregisters them.  A
43 There are also register_/unregister_*probes() functions for batch
44 registration/unregistration of a group of *probes. These functions
46 a lot of probes at once.
49 probes work and how jump optimization works.  They explain certain

327 function for each type of probe. The API also includes "register_*probes"
328 and "unregister_*probes" functions for (un)registering arrays of probes.
463 4.5 register_*probes
470 Registers each of the num probes in the specified array.  If any
471 error occurs during registration, all probes in the array, up to
472 the bad probe, are safely unregistered before the register_*probes
481 4.6 unregister_*probes
488 Removes each of the num probes in the specified array at once.
491 If the functions find some incorrect probes (ex. unregistered
492 probes) in the specified array, they clear the addr field of those
493 incorrect probes. However, other probes in the array are
518 Kprobes allows multiple probes at the same address.  Currently,
