Subject: [PATCH v2 01/17] KVM: async_pf: Move struct kvm_async_pf around
Date: Tue, 9 Feb 2021 13:03:47 +0800 [thread overview]
Message-ID: <20210209050403.103143-2-gshan@redhat.com> (raw)
In-Reply-To: <20210209050403.103143-1-gshan@redhat.com>
This moves the definitions of "struct kvm_async_pf" and the related
functions after "struct kvm_vcpu" so that newly added inline function
can dereference "struct kvm_vcpu" properly. Otherwise, the unexpected
build error will be raised:
error: dereferencing pointer to incomplete type ‘struct kvm_vcpu’
return !list_empty_careful(&vcpu->async_pf.done);
^~
The sepator between type and field is replaced by tab for "struct
kvm_async_pf" since we're here. This is preparatory work for adding
new inline function for next patch. This shouldn't cause logical
changes.
