Subject: [for-next][PATCH 18/32] tile: ftrace: Remove check of obsolete variable function_trace_stop
Date: Sat, 19 Jul 2014 09:15:42 -0400 [thread overview]
Message-ID: <20140719131612.511417886@goodmis.org> (raw)
In-Reply-To: 20140719131524.009152325@goodmis.org
[-- Attachment #1: 0018-tile-ftrace-Remove-check-of-obsolete-variable-functi.patch --]
[-- Type: text/plain, Size: 1842 bytes --]
From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>
Nothing sets function_trace_stop to disable function tracing anymore.
Remove the check for it in the arch code.
