From 3069211be30015b78e096fc4d3774b7d4ba29781 Mon Sep 17 00:00:00 2001 From: Coly Li Date: Sat, 11 Aug 2018 13:19:54 +0800 Subject: [PATCH] bcache: do not check NULL pointer before calling kmem_cache_destroy kmem_cache_destroy() is safe for NULL pointer as input, the NULL pointer checking is unncessary. This patch just removes the NULL pointer checking to make code simpler.
