Subject: [PATCH] zsmalloc: remove null check from destroy_handle_cache()
Date: Wed, 29 Jul 2015 23:26:58 +0900 [thread overview]
Message-ID: <1438180018-11773-1-git-send-email-sergey.senozhatsky@gmail.com> (raw)
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().
