The latest "arm64: untag > user pointers passed to the kernel" series doesn't untag these, thus we should > indicate here that these too are no supported. Yes.

I'll add something (unless someone has a real use-case for using tags with shmat/shmdt). -- Catalin _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
