OK, splice() cuts in at the file_operations level, so sych a clustered filesystem _could_ implement it, but none of the code we have there will be usable by it. If the operations in splice.c were to operate at the file_operations level (->read, ->write) then probably they could be used thusly. - 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/
