Subject: [PATCH v5 12/16] KVM: x86/pmu: Move pmc_speculative_in_use() to arch/x86/kvm/pmu.h
Date: Thu, 15 Apr 2021 11:20:12 +0800 [thread overview]
Message-ID: <20210415032016.166201-13-like.xu@linux.intel.com> (raw)
In-Reply-To: <20210415032016.166201-1-like.xu@linux.intel.com>
It allows this inline function to be reused by more callers in
more files, such as pmu_intel.c.
