Subject: [PATCH tracing/kprobes 4/4] tracing/kprobes: Change trace_arg to probe_arg
Date: Fri, 21 Aug 2009 19:41:00 -0000 [thread overview]
Message-ID: <20090821194351.12478.15247.stgit@localhost.localdomain> (raw)
In-Reply-To: <20090821000108.GC6078@nowhere>
Change trace_arg_string() and parse_trace_arg() to probe_arg_string()
and parse_probe_arg(), since those are kprobe-tracer local functions.
