Re: [PATCH 14/15] dax: associate mappings with inodes, and warn if dma collides with truncate

+ struct { + /* + * ZONE_DEVICE pages are never on an lru or handled by + * a slab allocator, this points to the hosting device + * page map. + */ + struct dev_pagemap *pgmap; + /* + * inode association for MEMORY_DEVICE_FS_DAX page-idle + * callbacks. Note that we don't use ->mapping since + * that has hard coded page-cache assumptions in + * several paths. + */
