Well, something that needs an almost one megabyte big wrapper per defintion is not a standalone work but something that's deeply interwinded with the kernel. The tons of kernel version checks certainly show it's poking deeper than it should. > Why do you believe that GPFS represents a kernel licensing violation? See above. Something that pokes deep into internal structures and even needs new exports certainly is a derived work. There's a few different interpretations of the derived works clause in the GPL around, the FSF one wouldn't allow binary modules at all, and Linus' one is also pretty strict. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
