Logic-wise it looks fine. I notice the “v6", and it should not be blocking, but I would note that the name "arch_tlbbatch_add_mm()” does not make much sense once the function also takes an address. It could’ve been something like arch_set_tlb_ubc_flush_pending() but that’s too long. I’m not very good with naming, but the current name is not great. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
