Subject: [PATCH v2 2/4] x86/kvm: Change print code to use pr_*() format
Date: Mon, 30 Sep 2019 20:08:58 +0800 [thread overview]
Message-ID: <1569845340-11884-3-git-send-email-zhenzhong.duan@oracle.com> (raw)
In-Reply-To: <1569845340-11884-1-git-send-email-zhenzhong.duan@oracle.com>
pr_*() is preferred than printk(KERN_* ...), after change all the print
in arch/x86/kernel/kvm.c will have "KVM: xxx" style.
No functional change.
