Long" Change kprobe_emulate_none, kprobe_simulate_nop, and arm_kprobe_decode_init function names to something more appropriate for code being shared outside of the kprobes subsystem. Also, move the new arm_probes_decode_init declaration out of the kprobes.h include file and into the probes.h include file. Signed-off-by: David A.
