Subject: [for-next][PATCH 22/32] MIPS: ftrace: Remove check of obsolete variable function_trace_stop
Date: Sat, 19 Jul 2014 09:15:46 -0400 [thread overview]
Message-ID: <20140719131613.241421466@goodmis.org> (raw)
In-Reply-To: 20140719131524.009152325@goodmis.org
[-- Attachment #1: 0022-MIPS-ftrace-Remove-check-of-obsolete-variable-functi.patch --]
[-- Type: text/plain, Size: 1543 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.
