From 549a715b98a13c6d05452be3ad37e980087bb081 Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Wed, 7 Dec 2022 00:09:59 +0000 Subject: KVM: x86: Add proper ReST tables for userspace MSR exits/flags Add ReST formatting to the set of userspace MSR exits/flags so that the resulting HTML docs generate a table instead of malformed gunk. This also fixes a warning that was introduced by a recent cleanup of the relevant documentation (yay copy+paste). >> Documentation/virt/kvm/api.rst:7287: WARNING: Block quote ends without a blank line; unexpected unindent.
