Subject: [PATCH v10 12/12] tracing: define trace_dump_stack() if !CONFIG_STACKTRACE
Date: Thu, 10 Oct 2013 19:48:36 -0500 [thread overview]
Message-ID: <b88c6631dc9bdd143e5fc19341954e42e59de128.1381445299.git.tom.zanussi@linux.intel.com> (raw)
In-Reply-To: <cover.1381445299.git.tom.zanussi@linux.intel.com>
In-Reply-To: <cover.1381445299.git.tom.zanussi@linux.intel.com>
If CONFIG_STACKTRACE is turned off, trace_dump_stack() isn't defined,
resulting in an 'undefined reference' error - define a stub to remedy
that.
