Subject: [PATCH] KVM: x86: Add proper ReST tables for userspace MSR exits/flags
Date: Wed, 7 Dec 2022 00:09:59 +0000 [thread overview]
Message-ID: <20221207000959.2035098-1-seanjc@google.com> (raw)
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).
