Message:

Define AS_AREA_NORESERVE and allow its use in the anonymous backend.

  • NORESERVE areas do not reserve physical memory in advance.
  • NORESERVE areas do not block while waiting for physical memory.
  • if a NORESERVE area cannot allocate a page of physical memory, it kills the task instantly
