Linux's 512 KB DIO limitation. I dont understand the 512 KB limitation that exists. I see that every every kiobuf has 1024 buffer heads allocated during alloc_kiovec. That means we should be able to transfer (1024 * blocksize) number of bytes. So why is KIO_MAX_ATOMIC_IO 512 KB? Thanks, Tridib -- Tridib Chakravarty tridib at
