Subject: [PATCH 07/12] Documentation: kvm: tdx-tdp-mmu: Use literal code block for EPT violation diagrams
Date: Sat, 9 Jul 2022 11:20:33 +0700 [thread overview]
Message-ID: <20220709042037.21903-8-bagasdotme@gmail.com> (raw)
In-Reply-To: <20220709042037.21903-1-bagasdotme@gmail.com>
EPT violation diagrams aren't inside literal code block, which trigger
"line block ends without a blank line" warning. Since these diagrams
aren't meant line blocks, use literal code block instead.
Fixes: 7af4efe3263854 ("KVM: x86: design documentation on TDX support of x86 KVM TDP MMU")
