Lorenzo Stoakes 6cdef2ddce fb_defio: do not use deprecated page->mapping, index fields ... With the introduction of mapping_wrprotect_range() there is no need to use folio_mkclean() in order to write-protect mappings of frame buffer pages, and therefore no need to inappropriately set kernel-allocated page->index, mapping fields to permit this operation. Instead, store the pointer to the page cache object for the mapped driver in the fb_deferred_io object, and use the already stored page offset from the pageref object to look up mappings in order to write-protect them. This is justified, as for the page objects to store a mapping pointer at the point of assignment of pages, they must all reference the same underlying address_space object. Since the life time of the pagerefs is also the lifetime of the fb_deferred_io object, storing the pointer here makes sense. This eliminates the need for all of the logic around setting and maintaining page->index,mapping which we remove. This eliminates the use of folio_mkclean() entirely but otherwise should have no functional change.
