Subject: [PATCH v1 2/4] KVM: arm64: Move KVM_VCPU_MAX_FEATURES to the features it is counting
Date: Mon, 14 Oct 2024 17:58:07 +0100 [thread overview]
Message-ID: <20241014165809.984883-3-tabba@google.com> (raw)
In-Reply-To: <20241014165809.984883-1-tabba@google.com>
Move KVM_VCPU_MAX_FEATURES to the header file that has the
features it is counting. Having it there reduces the chances of
missing to update it.
No functional change intended.
