Subject: [PATCH v5 17/37] tracing: Move get_hist_field_flags()
Date: Thu, 9 Nov 2017 14:33:48 -0600 [thread overview]
Message-ID: <2148919f16218fa4fe8da1d01504ea4cdd3dea3d.1510252666.git.tom.zanussi@linux.intel.com> (raw)
In-Reply-To: <cover.1510252666.git.tom.zanussi@linux.intel.com>
In-Reply-To: <cover.1510252666.git.tom.zanussi@linux.intel.com>
Move get_hist_field_flags() to make it more easily accessible for new
code (and keep the move separate from new functionality).
