Subject: [PATCH 2/2] KVM: LAPIC: remove the trailing newline used in the fmt parameter of TP_printk
Date: Thu, 23 May 2019 12:18:51 +0800	[thread overview]
Message-ID: <1558585131-1321-2-git-send-email-wanpengli@tencent.com> (raw)
In-Reply-To: <1558585131-1321-1-git-send-email-wanpengli@tencent.com>

From: Wanpeng Li <wanpengli@tencent.com>

The trailing newlines will lead to extra newlines in the trace file 
which looks like the following output, so remove it.

qemu-system-x86-15695 [002] ...1 15774.839240: kvm_hv_timer_state: vcpu_id 0 hv_timer 1

qemu-system-x86-15695 [002] ...1 15774.839309: kvm_hv_timer_state: vcpu_id 0 hv_timer 1
