Subject: [GIT PULL] erofs updates for 6.5-rc1

Hi Linus,

Could you consider this pull request for 6.5-rc1?

No outstanding new feature available for this cycle.  Most of these
commits are decompression cleanups which are part of the ongoing
development for subpage/folio compression support as well as xattr
cleanups for the upcoming xattr bloom filter optimization [1].

In addition, there are bugfixes to address some corner cases of
compressed images due to global data de-duplication and arm64 16k
pages.

All commits have been in -next for a while and no potential merge
conflict is observed.

Thanks,
Gao Xiang
