This kind of started off as a gfs2 patch series, then became entwined

the big point of this series is that block_write_full_page() should now
handle large folios correctly.
It probably makes most sense to take this through Andrew's tree, once
enough people have signed off on it?

gfs2: Use a folio inside gfs2_jdata_writepage()
gfs2: Pass a folio to __gfs2_jdata_write_folio()
gfs2: Convert gfs2_write_jdata_page() to gfs2_write_jdata_folio()
buffer: Convert __block_write_full_page() to
__block_write_full_folio()
gfs2: Support ludicrously large folios in gfs2_trans_add_databufs()
buffer: Make block_write_full_page() handle large folios correctly

Hi Matthew,
I recently started looking into doing this, too, so this is apropos.
I'll give it a careful review and some testing. The jdata stuff in gfs2
is very touchy, but this looks like a step in the right direction.
I'll let you know how it fares.
Regards,
Bob Peterson
