TODO: - Documentation [Sean?] - Changelogs [Sean] - Non-filemap implementation [Paolo] - Hugepage tests (verify KVM actually installs hugepages as expected) - Memory failure tests (e.g. synthetic #MC injection) - Get Input from IOMMU / VFIO [Paolo] Opens: - .release_folio and .invalidate_folio versus .evict_inode [Mike] - Fully anonymous inode vs. proper filesystem [Sean / Paolo] - HugeTLB (or something similar) support [Future] - Intrahost migration support [Google GCE] - NUMA support [ TBD - implement fbind() ] - Memory Accounting [Sean - should Just Work, keyword should ] - Page Table Accounting - Should we?
