In man page, there is following statement.
"status is an array of integers that return the status of each page.  The array
only contains valid values if move_pages() did not return an error."

And current implementation of move_pages() syscall doesn't return the number
of pages not moved, just return 0 when it encounter some failed pages.
So, if u want to fix the man page, u should fix do_pages_move() first.

Hmm... Yeah actually that is sufficient since the status is readily
obtainable from the status array. It would be better though if the
function would return the number of pages not moved in the same way as
migrate_pages().
