From 0c81248bf46f611b56e3ab38b4d83e449b3c8636 Mon Sep 17 00:00:00 2001 From: Dave Cheney Date: Wed, 6 Apr 2016 18:43:23 +1000 Subject: runtime: remove unused return value from lfstackUnpack None of the two places that call lfstackUnpack use the second argument. This simplifies a followup CL that merges the lfstack{Pack,Unpack} implementations.
