Subject: [PATCH 2/4] powerpc: Rename is_kvm_guest to check_kvm_guest
Date: Wed, 28 Oct 2020 18:05:10 +0530 [thread overview]
Message-ID: <20201028123512.871051-3-srikar@linux.vnet.ibm.com> (raw)
In-Reply-To: <20201028123512.871051-1-srikar@linux.vnet.ibm.com>
is_kvm_guest() will be reused in subsequent patch in a new avatar. Hence
rename is_kvm_guest to check_kvm_guest. No additional changes.
