Subject: [PATCH v2 0/2] erofs: support large folios for fscache mode

v2:
- patch 2: keep the enabling for iomap and fscache mode in separate
  patches; don't enable the feature for the meta data routine for now
  (Gao Xiang)

v1: https://lore.kernel.org/all/20221126005756.7662-1-jefflexu@linux.alibaba.com/


Patch 1 is the main part of supporting large folios for 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 for fscache
mode. It relies on a previous patch[2] which enables this feature for
iomap mode.
