| |
The return value of kvm_emulate_hypercall() is intended to inform callers whether or not we need to exit to userspace. However, handle_vmcall() currently ignores the return value.
This patch simply propogates the return value from kvm_emulate_hypercall() to callers so that it can be acted upon appropriately.
