[PATCH 0/2] erofs: support large folio in fscache mode

Patch 1 is the main part of supporting large folio in fscache mode. It
relies on a pending patch[1] adding .prepare_ondemand_read() interface
in Cachefiles.

Patch 2 just turns the switch on and enables the feature. It enables large
folio for both fscache and the original device mode (in uncompressed
data format). And thus I think the previous patch[2] exclusively for the
device mode is not needed then.
