Can you guys please revert 4fd466eb46a6 ("HWPOISON: add memory cgroup filter"), which reaches into cgroup to extract the inode number and uses that for filtering? Nobody outside cgroup proper should be reaching into that. In fact, the hard association between vfs objects and cgroup objects are going away in the upcoming devel cycle. If you want to tag on memcg for filtering, please introduce a proper memcg knob. Thank you. -- tejun -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
