[PATCH 1/4] KVM: PPC: Pass change type down to memslot commit function

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

 



From: Bharata B Rao <bharata@xxxxxxxxxxxxx>

Currently, kvm_arch_commit_memory_region() gets called with a
parameter indicating what type of change is being made to the memslot,
but it doesn't pass it down to the platform-specific memslot commit
functions.  This adds the `change' parameter to the lower-level
functions so that they can use it in future.
