Message-Id: <20190327141946.4353-3-tstoyanov@vmware.com>
Date: Wed, 27 Mar 2019 16:19:43 +0200
From: Tzvetomir Stoyanov <tstoyanov@...are.com>
To: rostedt@...dmis.org
Cc: linux-trace-devel@...r.kernel.org, linux-kernel@...r.kernel.org
Subject: [PATCH v2 2/5] tools/lib/traceevent: Rename input arguments of libtraceevent APIs from pevent to tep
This patch renames "struct tep_handle *pevent" input arguments of libtraceevent
APIs to "struct tep_handle *tep". This makes the API consistent with the chosen
naming convention: tep (trace event parser), instead of the old pevent.
Signed-off-by: Tzvetomir Stoyanov <tstoyanov@...are.com>
