From cd10add00c1b31cd664a31108a9b395025def50a Mon Sep 17 00:00:00 2001 From: Sergey Senozhatsky Date: Tue, 8 Sep 2015 15:04:55 -0700 Subject: [PATCH] zsmalloc: remove null check from destroy_handle_cache() We can pass a NULL cache pointer to kmem_cache_destroy(), because it NULL-checks its argument now. Remove redundant test from destroy_handle_cache().
