Hi
In my opinion, pfn_valid() is meant to be able to tell if a given PFN has valid
section, and That section can contain corresponding mem_map. but, the section can
be has holes, the corresponding mem_map also be allcoated, resulting in treating
the PFN as valid incorrect.
what's problem for the interpretation of the above?
