Subject: [PATCH 0/5] erofs: get rid of erofs_get_meta_page()
Date: Wed, 29 Dec 2021 12:14:00 +0800	[thread overview]
Message-ID: <20211229041405.45921-1-hsiangkao@linux.alibaba.com> (raw)

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
