Konstantin Belousov d3b9828d0d The vmtotal sysctl handler marks active vm objects to calculate ... statistics. Marking is done by setting the OBJ_ACTIVE flag. The flags change is locked, but the problem is that many parts of system assume that vm object initialization ensures that no other code could change the object, and thus performed lockless. The end result is corrupted flags in vm objects, most visible is spurious OBJ_DEAD flag, causing random hangs. Avoid the active object marking, instead provide equally inexact but immutable is_object_alive() definition for the object mapped state. Avoid iterating over the processes mappings altogether by using arguably improved definition of the paging thread as one which sleeps on the v_free_count.
