Thanks, It works with v4 patch.

Well, page_stats / page_items does accept bitmap page as input but
these function are not defined to read bitmap page as bitmap page
doesnot have a standard page layout. Infact if we pass bitmap page as
an input to page_stats / page_items, the output is always same. I
think we need to have a separete function to read bitmap page. And i
am not sure why should a server crash if i pass meta page to
hash_page_stats or hash_page_items.

Not sure if CHI patch is adding a new type of hash page other than
holding an information about split in progress. Basically my point was
can we have hash page of types other than meta page, bucket page,
overflow and bitmap page. If pageinspect tool finds a page that
doesnot fall under any of these category shouldn't it error out.
