From f0231305acd53375c6cf736971bf5711105dd6bb Mon Sep 17 00:00:00 2001 From: Miaohe Lin Date: Thu, 25 Feb 2021 17:18:27 -0800 Subject: mm/zsmalloc.c: convert to use kmem_cache_zalloc in cache_alloc_zspage() We always memset the zspage allocated via cache_alloc_zspage. So it's more convenient to use kmem_cache_zalloc in cache_alloc_zspage than caller do it manually.
