[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH 02/17] x86/hvm: re-name struct hvm_mmio_handler to hvm_mmio_ops
The struct just contains three methods and no data, so the name
hvm_mmio_ops more accurately reflects its content. A subsequent patch
introduces a new structure which more accurately warrants the name
hvm_mmio_handler so doing the rename in this purely cosmetic patch avoids
conflating functional and cosmetic changes in a single patch.
