truncation, punch hole or a complete invalidation of the address
space (in the latter case 'offset' will always be 0 and 'length'
will be PAGE_CACHE_SIZE). Any private data associated with the page
will be PAGE_SIZE). Any private data associated with the page
should be updated to reflect this truncation. If offset is 0 and
length is PAGE_CACHE_SIZE, then the private data should be released,
length is PAGE_SIZE, then the private data should be released,
because the page must be able to be completely discarded. This may
be done by calling the ->releasepage function, but in this case the
release MUST succeed.
