Subject: [PATCH v4 2/4] KVM: Define KVM_MEMSLOTS_NUM_MAX_DEFAULT
Date: Tue, 17 Sep 2024 12:38:33 -0400 [thread overview]
Message-ID: <20240917163835.194664-3-peterx@redhat.com> (raw)
In-Reply-To: <20240917163835.194664-1-peterx@redhat.com>
Make the default max nr_slots a macro, it's only used when KVM reports
nothing.
