[PATCH 09/12] Documentation: kvm: tdx-tdp-mmu: Add blank line padding to lists in concurrent sections

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The last warnings on tdx-tdp-mmu.rst are caused by missing blank line
padding at lists on "concurrent" sections. Add the padding.

Fixes: 7af4efe3263854 ("KVM: x86: design documentation on TDX support of x86 KVM TDP MMU")
