Subject: [PATCH v6 07/21] tracing: probeevent: Remove NOKPROBE_SYMBOL from print functions
Date: Sat, 17 Mar 2018 21:42:44 +0900
Message-ID: <152129056480.31874.12788717040043254904.stgit@devbox> (raw)
In-Reply-To: <152129024033.31874.15800253385376959274.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.
