[PATCH] kvm: x86: disable the narrow guest module parameter on unload

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When the kvm_intel module unloads the module parameter
'allow_smaller_maxphyaddr' is not cleared because it is also used in the
kvm module.  As a result, if the module parameter's state was set before
kvm_intel unloads, it will also be set when it reloads.  Explicitly
clear the state in vmx_exit() to prevent this from happening.
