[PATCH v5 01/15] stacktrace/x86: add function for detecting reliable stack traces

2017-02-13 Thread Josh Poimboeuf
For live patching and possibly other use cases, a stack trace is only useful if it can be assured that it's completely reliable. Add a new save_stack_trace_tsk_reliable() function to achieve that. Note that if the target task isn't the current task, and the target task is allowed to run, then it
