From 98c98cb770da9469ee868f21299b2ba21fe438ac Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Wed, 14 Nov 2018 22:17:05 +0000 Subject: [PATCH] block: clean up dead code that is now redundant The boolean next_sorted is set to false and is never changed, hence the code that checks if it is true is dead code and can now be removed. This dead code occurred from a previous commit that cleaned up the elevator and removed the setting of next_sorted to true.
