Subject: [PATCH 2/6] x86/kvm: Rename the KVM private read_msr() function
Date: Tue, 6 May 2025 11:20:11 +0200 [thread overview]
Message-ID: <20250506092015.1849-3-jgross@suse.com> (raw)
In-Reply-To: <20250506092015.1849-1-jgross@suse.com>
Avoid a name clash with a new general MSR access helper after a future
MSR infrastructure rework by renaming the KVM specific read_msr() to
kvm_read_msr().
