It's a bit of a sledge hammer... Since get_user_pages() appears to work on nummu, we can just disable the vmsplice-to-userspace bits and leave the (working) vmsplice-from-userspace in place. I'm reworking this code anyway in the block branches, so I'll update and take CONFIG_MMU into consideration. -- Jens Axboe - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
