Add CONFIG_HAVE_KRETPROBES to the arch/<arch>/Kconfig file for relevant architectures with kprobes support. This facilitates easy handling of in-kernel modules (like samples/kprobes/kretprobe_example.c) that depend on kretprobes being present in the kernel. Thanks to Sam Ravnborg for helping make the patch more lean. Per Mathieu's suggestion, added CONFIG_KRETPROBES and fixed up dependencies.

and applications.

Kprobes allows you to trap at almost any kernel address and
|
|
execute a callback function. register_kprobe() establishes
|
|
a probepoint and specifies the callback. Kprobes is useful
|
|
for kernel debugging, non-intrusive instrumentation and testing.
|
|
If in doubt, say "N".
