Subject: [PATCH v7 03/16] KVM: x86: Use file_to_kvm_x86() in SEV
Date: Thu,  8 Oct 2026 11:29:42 +0530	[thread overview]
Message-ID: <20261008055955.4014342-4-aneesh.kumar@kernel.org> (raw)
In-Reply-To: <20261008055955.4014342-1-aneesh.kumar@kernel.org>

From: Steffen Eiden <seiden@linux.ibm.com>

Use the new arch-namespaced helper instead of open-coding the file check
and private_data cast separately.

Suggested-by: Sean Christopherson <seanjc@google.com>
