From 3b6cfdb1714a33ae4d2ca9fbc818a42cf7adee69 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Mon, 23 May 2011 15:33:49 -0400 Subject: [PATCH] ftrace: Set ops->flag to enabled even on static function tracing When dynamic ftrace is not configured, the ops->flags still needs to have its FTRACE_OPS_FL_ENABLED bit set in ftrace_startup().
