Message-Id: <1311406305-24523-1-git-send-email-mikew@google.com> Date: Sat, 23 Jul 2011 00:31:45 -0700 From: Mike Waychison <mikew@...gle.com> To: Avi Kivity <avi@...hat.com>, Marcelo Tosatti <mtosatti@...hat.com> Cc: x86@...nel.org, kvm@...r.kernel.org, linux-kernel@...r.kernel.org, Mike Waychison <mikew@...gle.com> Subject: [PATCH] kvm: Really fix HV_X64_MSR_APIC_ASSIST_PAGE Commit 0945d4b228 tried to fix the get_msr path for the HV_X64_MSR_APIC_ASSIST_PAGE msr, but was poorly tested. We should be returning 0 if the read succeeded, and passing the value back to the caller via the pdata out argument, not returning the value directly.
