Subject: [PATCH v5 08/20] KVM: arm/arm64: Rename soft timer to bg_timer
Date: Fri, 27 Oct 2017 10:34:29 +0200	[thread overview]
Message-ID: <1509093281-15225-9-git-send-email-cdall@linaro.org> (raw)
In-Reply-To: <1509093281-15225-1-git-send-email-cdall@linaro.org>

As we are about to introduce a separate hrtimer for the physical timer,
call this timer bg_timer, because we refer to this timer as the
background timer in the code and comments elsewhere.
