[PATCH 0/3] tracing/kprobes: Fix event generation API etc.

[Masami Hiramatsu <mhiramat@kernel.org>]

Hello,

Here are bugfix/cleanup patches for the kprobe tracer, [1/3]
is a typo fix, [2/3] is fixing boot-time tracer and [3/3] is
error checking for the new in-kernel kprobe event API.

Tom, I found that your commit 29a154810546 ("tracing: Change
trace_boot to use kprobe_event interface") broke the boot-time
tracer's kprobe event because of wrong API usage. Could you
review it?

I marked [3/3] as a bugfix, because if the loc == NULL, 
__kprobe_event_gen_cmd_start() obviously does not work.
But it reports actual error at kprobe_event_gen_cmd_end().
That is not good for developers to debug it.

Thank you,
