Subject: [PATCH v2 03/14] KVM: arm: Make vcpu finalization stubs into inline functions
Date: Thu, 18 Apr 2019 17:07:00 +0100 [thread overview]
Message-ID: <1555603631-8107-4-git-send-email-Dave.Martin@arm.com> (raw)
In-Reply-To: <1555603631-8107-1-git-send-email-Dave.Martin@arm.com>
The vcpu finalization stubs kvm_arm_vcpu_finalize() and
kvm_arm_vcpu_is_finalized() are currently #defines for ARM, which
limits the type-checking that the compiler can do at runtime.
The only reason for them to be #defines was to avoid reliance on
the definition of struct kvm_vcpu, which is not available here due
to circular #include problems. However, because these are stubs
containing no code, they don't need the definition of struct
kvm_vcpu after all; only a declaration is needed (which is
available already).
So in the interests of cleanliness, this patch converts them to
inline functions.
No functional change.
