From: Christoph Hellwig <hch@xxxxxx> Subject: samples/vfio-mdev/mdpy: use remap_vmalloc_range Patch series "remap_vmalloc_range cleanups". This series removes an open coded instance of remap_vmalloc_range and removes the unused remap_vmalloc_range_partial export. This patch (of 2): Use remap_vmalloc_range instead of open coding it using remap_vmalloc_range_partial.
