If you don't initialize the entire structure and you use it all, of course you get undefined behavior. That's nothing new. The program I attached is not an example, it's a test for the functionality in this patch. Like with every kernel interface, you have to use it correctly. The good news is that user programs should never use this syscall directly (just like don't for existing ones). I see no problem at all here. - -- ➧ Ulrich Drepper ➧ Red Hat, Inc. ➧ 444 Castro St ➧ Mountain View, CA ❖ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) iD8DBQFHQbBH2ijCOnn/RHQRAkc3AKCxVTWQ3BiQnCBwdbAsT122QWWaiwCggKXN Z5Sz9/NFojMHZXXTzIMoxX4= =slte -----END PGP SIGNATURE----- - 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/
