From f588557ac4aceccded4741dfdb18336e39c7a208 Mon Sep 17 00:00:00 2001 From: Anish Moorthy Date: Thu, 15 Feb 2024 23:53:55 +0000 Subject: KVM: Simplify error handling in __gfn_to_pfn_memslot() KVM_HVA_ERR_RO_BAD satisfies kvm_is_error_hva(), so there's no need to duplicate the "if (writable)" block. Fix this by bringing all kvm_is_error_hva() cases under one conditional.
