[PATCH 3/3] KVM: remove redundant assignments in __kvm_set_memory_region

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

 



__kvm_set_memory_region sets r to EINVAL very early.
Doing it again is not necessary. The same is true later on, where
r is assigned -ENOMEM twice.
