Subject: [PATCH v2 2/4] KVM: Define KVM_MEMSLOTS_NUM_MAX_DEFAULT
Date: Wed, 4 Sep 2024 18:35:08 -0400 [thread overview]
Message-ID: <20240904223510.3519358-3-peterx@redhat.com> (raw)
In-Reply-To: <20240904223510.3519358-1-peterx@redhat.com>
Make the default max nr_slots a macro, it's only used when KVM reports
nothing.
