From bf255bdaada6d497536aadee5406f6ded318978b Mon Sep 17 00:00:00 2001 From: Josh Poimboeuf Date: Thu, 18 Aug 2016 10:59:01 -0500 Subject: [PATCH] x86/dumpstack: Remove show_trace() There are a bewildering array of options for dumping the stack. Simplify things a little by removing show_trace(), which is unused.
