[PATCH 0/5] erofs: get rid of erofs_get_meta_page()

[Gao Xiang]

Hi folks,

erofs_get_meta_page() is actually inflexible since it's too
close to the page itself.

In order to prepare for folio and subpage features, introduce
on-stack meta buffer descriptor instead and convert all
erofs_get_meta_page() users to use it.

It can also be used for new potential backends such as fscache or mtd.

Patches are trivial.

Thanks,
Gao Xiang
