From: Guillaume Thouvenin Date: Tue, 27 May 2008 08:18:46 +0000 (+0200) Subject: KVM: Prefixes segment functions that will be exported with "kvm_" X-Git-Tag: v2.6.27-rc1~968^2~48 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3e6e0aab1ba1e8b354ce01f5659336f9aee69437;p=linux-2.6 KVM: Prefixes segment functions that will be exported with "kvm_" Prefixes functions that will be exported with kvm_. We also prefixed set_segment() even if it still static to be coherent. signed-off-by: Guillaume Thouvenin Signed-off-by: Laurent Vivier Signed-off-by: Avi Kivity --- diff --git a/arch/x86/kvm/x86.c b/arch/x86/kvm/x86.c index 5f67a7c54e..4c94fad7f0 100644 --- a/arch/x86/kvm/x86.c +++ b/arch/x86/kvm/x86.c @@ -3100,8 +3100,8 @@ int kvm_arch_vcpu_ioctl_set_regs(struct kvm_vcpu *vcpu, struct kvm_regs *regs) return 0;
