From 9b36eda4dfe0bcd76233b3f1318b66478c1d0698 Mon Sep 17 00:00:00 2001 From: Fuad Tabba Date: Mon, 6 Jul 2026 11:31:28 +0100 Subject: [PATCH] KVM: arm64: Remove unreachable early checks in pkvm_init_host_vm() pkvm_init_host_vm() runs once from kvm_arch_init_vm(), while the VM is still being allocated and is not yet reachable by another thread. Both early checks therefore test impossible state: is_created is still false (it is only set on first vCPU run) and the handle is still zero (this function is what reserves it). Neither branch can be taken. Remove them.
