The pagebuf layer presents and inferface similar enough to the IRIX buffercache to XFS and is layered ontop of the Linux pagecache. Today it's only used for metadata and allows mapping of > PAGE_CACHE_SIZE objects there (see the vmap/vunmap code I added to vmalloc.c in 2.5 for that). But it's not used for data I/O at all anymore and it would also have problems for blocksize > PAGE_CACHE_SIZE. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
