From fe3c2b4c228443b505f2d8981c4871b96cfec6d6 Mon Sep 17 00:00:00 2001 From: Miaohe Lin Date: Thu, 5 Dec 2019 11:40:16 +0800 Subject: [PATCH] KVM: explicitly set rmap_head->val to 0 in pte_list_desc_remove_entry() When we reach here, we have desc->sptes[j] = NULL with j = 0. So we can replace desc->sptes[0] with 0 to make it more clear.
