Subject: [for-next][PATCH 06/12] trace: rename trace_enum_mutex to trace_eval_mutex
Date: Thu, 15 Jun 2017 06:52:29 -0400	[thread overview]
Message-ID: <20170615105253.537390734@goodmis.org> (raw)
In-Reply-To: 20170615105223.551999981@goodmis.org

[-- Type: text/plain, Size: 2396 bytes --]

From: Jeremy Linton <jeremy.linton@arm.com>

There is a lock protecting the trace_enum_map, rename
it to reflect the use by more than enums.
