Subject: [PATCH 12/12] ftrace: Set ops->flag to enabled even on static function tracing
Date: Tue, 24 May 2011 14:10:44 -0400 [thread overview]
Message-ID: <20110524181722.124131254@goodmis.org> (raw)
In-Reply-To: 20110524181032.382259739@goodmis.org
[-- Attachment #1: 0012-ftrace-Set-ops-flag-to-enabled-even-on-static-functi.patch --]
[-- Type: text/plain, Size: 1062 bytes --]
From: Steven Rostedt <srostedt@redhat.com>
When dynamic ftrace is not configured, the ops->flags still needs
to have its FTRACE_OPS_FL_ENABLED bit set in ftrace_startup().
