From acf421755593f7d7bd9352d57eda796c6eb4fa43 Mon Sep 17 00:00:00 2001 From: Dave Jones Date: Mon, 12 Jun 2006 14:20:58 +0200 Subject: [PATCH] [PATCH] remove dead code from elevator switching We already drop the refcount in elevator_exit(), and as we're setting 'e' to NULL, we'll never take that branch anyway. Finally, as 'e' is a local var that isn't referenced afterwards, setting it to NULL is pointless.
