I didn't see that report. Was that some odd x86 Android setup > with Ashmem too, or is there something else pending? I've got report from youling privately: "mm: fix vma_is_anonymous() false-positives" cause my userspace boot failed， our Androidx86 userspace can running on linux mainline kernel， revert it boot succeed with 4.18rc7 kernel.
