I was hoping to come back to fixing swapfile support for cifs.ko in 6.10-rc (which used to pass the various xfstests for this but code got removed with folios/netfs changes).

Hi Steven,
I think this won't cause any trouble for that, the new swap_rw
interface should have splitted the swap cache from fs side, which made
the code struct cleaner, and I think that's the right path. NFS is
using that already. With this interface, .read_folio (cifs_read_folio)
should never be called for swap cache folios.
