I think this may be the last batch of patches to gfs2 for folio conversions. The only remaining references to struct page that I see are for filesystem metadata that isn't stored in the page cache, so those are fine to continue using struct page. The only mild improvement would be if we could have different bio completion handlers for gfs2_end_log_write() when it's using mempool pages vs folio pages, but that may not even be feasible and I like the current solution well enough. This all seems fairly straightforward to me, but as usual only compile-tested. I don't anticipate the change to buffer_head.h to have any conflicts; removing the last user of page_buffers() is not on the cards for the next merge window.
