From a1c42ddedf35dbf5f25ea0982ed6e226eef7a78c Mon Sep 17 00:00:00 2001 From: Juergen Gross Date: Mon, 13 Sep 2021 15:57:44 +0200 Subject: kvm: rename KVM_MAX_VCPU_ID to KVM_MAX_VCPU_IDS KVM_MAX_VCPU_ID is not specifying the highest allowed vcpu-id, but the number of allowed vcpu-ids. This has already led to confusion, so rename KVM_MAX_VCPU_ID to KVM_MAX_VCPU_IDS to make its semantics more clear Suggested-by: Eduardo Habkost Signed-off-by: Juergen Gross Signed-off-by: Paolo Bonzini Message-Id: <20210913135745.13944-3-jgross@suse.com> Signed-off-by: Paolo Bonzini --- arch/mips/kvm/mips.c | 2 +- arch/powerpc/include/asm/kvm_book3s.h | 2 +- arch/powerpc/include/asm/kvm_host.h | 4 ++-- arch/powerpc/kvm/book3s_xive.c | 2 +- arch/powerpc/kvm/powerpc.c | 2 +- arch/x86/include/asm/kvm_host.h | 2 +- arch/x86/kvm/ioapic.c | 2 +- arch/x86/kvm/ioapic.h | 4 ++-- arch/x86/kvm/x86.c | 2 +- 9 files changed, 11 insertions(+), 11 deletions(-) (limited to 'arch') diff --git a/arch/mips/kvm/mips.c b/arch/mips/kvm/mips.c index 75c6f264c626..562aa878b266 100644 --- a/arch/mips/kvm/mips.c +++ b/arch/mips/kvm/mips.c @@ -1073,7 +1073,7 @@ int kvm_vm_ioctl_check_extension(struct kvm *kvm, long ext) r = KVM_MAX_VCPUS;
