See linux/kernel/user.c I guess it would be trivial to use it for mlock too. Of course you still want a global limit too. Having a few pages mlockable per user per defalt would be very useful for cryptographic software that does not want its keys stored on the swap partition. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.rutgers.edu Please read the FAQ at http://www.tux.org/lkml/
