Subject: [PATCH v8 17/22] tracing: Remove unnecessary hist trigger struct fields
Date: Mon, 10 Dec 2018 18:01:31 -0600 [thread overview]
Message-ID: <725804f4cd0e90ee3f19048e195e0bff08a189a8.1544483273.git.tom.zanussi@linux.intel.com> (raw)
In-Reply-To: <cover.1544483272.git.tom.zanussi@linux.intel.com>
In-Reply-To: <cover.1544483272.git.tom.zanussi@linux.intel.com>
From: Tom Zanussi <tom.zanussi@linux.intel.com>
track_data->var_ref->var_ref_idx can be used instead of
track_data.var_ref_idx, so remove it.
Also, hist_field.var_idx is completely unused, so remove it too.
