From 77b44d1b7c28360910cdbd427fb62d485c08674c Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Tue, 3 Nov 2009 19:12:47 -0500 Subject: tracing/kprobes: Rename Kprobe-tracer to kprobe-event Rename Kprobes-based event tracer to kprobes-based tracing event (kprobe-event), since it is not a tracer but an extensible tracing event interface. This also changes CONFIG_KPROBE_TRACER to CONFIG_KPROBE_EVENT and sets it y by default.
