Subject: [PATCH v7 03/16] tracing: probeevent: Remove NOKPROBE_SYMBOL from print functions
Date: Wed, 25 Apr 2018 21:17:34 +0900 [thread overview]
Message-ID: <152465865422.26224.10111548170594014954.stgit@devbox> (raw)
In-Reply-To: <152465856498.26224.16969986455942749517.stgit@devbox>
Remove unneeded NOKPROBE_SYMBOL from print functions since
the print functions are only used when printing out the
trace data, and not from kprobe handler.
