Subject: [PATCH] KVM: VMX: replace "fall through" with "return true" to indicate different case
Date: Tue, 18 Feb 2020 11:39:28 +0800 [thread overview]
Message-ID: <1581997168-20350-1-git-send-email-linmiaohe@huawei.com> (raw)
From: Miaohe Lin <linmiaohe@huawei.com>
The second "/* fall through */" in rmode_exception() makes code harder to
read. Replace it with "return true" to indicate they are different cases
and also this improves the readability.
