From: Steven Rostedt <rostedt@goodmis.org> Add a function that must be called inside a faultable context that will retrieve a user space stack trace. The function unwind_deferred_trace() can be called by a tracer when a task is about to enter user space, or has just come back from user space and has interrupts enabled.
