Should I drop access_ok() change from my patch, since yours just reverts it?Not necessary, your patch just relaxes the ABI for all apps, mine tightens it. You could instead move the untagging to __range_ok() and rebase my patch accordingly.OK, will do. I'll also add a comment next to TIF_TAGGED_ADDR as Vincenzo asked.
Thanks. -- Catalin _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
