2014-09-26kprobes: update jprobe_example.c for do_fork() changeMichael Ellerman
In commit e80d666 "flagday: kill pt_regs argument of do_fork()", the arguments to do_fork() changed. The example code in jprobe_example.c was not updated to match, so the arguments inside the jprobe handler do not match reality. Fix it by updating the arguments to match do_fork(). While we're at it use pr_info() for brevity, and print stack_start as well for interest.

2010-08-05SAMPLES: kprobe_example: Make it print something on MIPS.David Daney
This KProbes example is a little useless if it doesn't print anything. For MIPS print similar messages to those produced on x86 and PPC.

2008-03-04Kprobes: move kprobe examples to samples/Ananth N Mavinakayanahalli
Move kprobes examples from Documentation/kprobes.txt to under samples/. Patch originally by Randy Dunlap. o Updated the patch to apply on 2.6.25-rc3 o Modified examples code to build on multiple architectures. Currently, the kprobe and jprobe examples code works for x86 and powerpc o Cleaned up unneeded #includes o Cleaned up Kconfig per Sam Ravnborg's suggestions to fix build break on archs that don't have kretprobes o Implemented suggestions by Mathieu Desnoyers on CONFIG_KRETPROBES o Included Andrew Morton's cleanup based on x86-git o Modified kretprobe_example to act as a arch-agnostic module to determine routine execution times: Use 'modprobe kretprobe_example func=<func_name>' to determine execution time of func_name in nanoseconds.
