Subject: [for-next][PATCH 17/46] tracing: Move get_hist_field_flags()
Date: Tue, 20 Mar 2018 22:21:09 -0400 [thread overview]
Message-ID: <20180321022126.019682423@goodmis.org> (raw)
In-Reply-To: 20180321022052.030055576@goodmis.org
[-- Attachment #1: 0017-tracing-Move-get_hist_field_flags.patch --]
[-- Type: text/plain, Size: 2606 bytes --]
From: Tom Zanussi <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).
