[PATCH] kvm: Provide kvm_vcpu_eligible_for_directed_yield() stub

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

 



Commit 7940876e1330671708186ac3386aa521ffb5c182 ("kvm: make local
functions static") broke KVM PPC builds due to removing (rather than
moving) the stub version of kvm_vcpu_eligible_for_directed_yield().

This patch reintroduces it.
