Subject: [RFA][PATCH 17/27] tile: ftrace: Remove check of obsolete variable function_trace_stop
Date: Thu, 26 Jun 2014 12:52:38 -0400 [thread overview]
Message-ID: <20140626165852.012558348@goodmis.org> (raw)
In-Reply-To: <20140626165221.736847419@goodmis.org>
[-- Attachment #1: 0017-tile-ftrace-Remove-check-of-obsolete-variable-functi.patch --]
[-- Type: text/plain, Size: 1840 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.
[ Please test this on your arch ]
