It's definitely not a stable ABI. slabtop tends to exit without any error message on any slabinfo version number increase and I've seen that happen several times in not so old kernels. Requiring just another slabtop update isn't really a big deal. Also it's not that it's a critical functionality like udev. -Andi -- 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/
