There is no need to prohibit probing on the functions used in preparation phase. Those are safely probed because those are not invoked from breakpoint/fault/debug handlers, there is no chance to cause recursive exceptions. Following functions are now removed from the kprobes blacklist: can_boost can_probe can_optimize is_IF_modifier __copy_instruction copy_optimized_instructions arch_copy_kprobe arch_prepare_kprobe arch_arm_kprobe arch_disarm_kprobe arch_remove_kprobe arch_trampoline_kprobe arch_prepare_kprobe_ftrace arch_prepare_optimized_kprobe arch_check_optimized_kprobe arch_within_optimized_kprobe __arch_remove_optimized_kprobe arch_remove_optimized_kprobe arch_optimize_kprobes arch_unoptimize_kprobe I tested those functions by putting kprobes on all instructions in the functions with the bash script I sent to LKML.
