Because we already have such a syscall (ioctl) and we see the trouble it causes all over the place. Design yur interfaces properly instead.

So do it know. It's possible and it just shows you've sent the LSM crap without actually thinking about a better design. Come back when you have a proper design.
and btw, as LSM is part of the kernel anyone can and will change it. Your LSM team attitude is a bit like that hated CVS mentality.. - 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/
