Hi folks,

Now I'm working on cleanuping decompression code and doing some
folio adaption for the next 5.20 cycle, see:

https://git.kernel.org/pub/scm/linux/kernel/git/xiang/linux.git/log/?h=erofs/folios

This cleanup work completely gets rid of PageError usage finally
and tries to prepare for introducing rolling hashing for EROFS
since EROFS supports compressing variable-sized data instead of
fixed-sized clusters.

Therefore, EROFS can support rolling hash easily and our mechanism
can make full use of filesystem interfaces (byte-addressed) naturally.

Before that, I'd like to submit some trivial cleanups in advance for
the 5.19 cycle. All patches are without any logical change, so I can
have a more recent codebase for the next rework cycle.

Thanks,
Gao Xiang
