[GIT PULL] erofs updates for 6.8-rc1

[Gao Xiang]

Hi Linus,

Could you consider this pull request for 6.8-rc1?

In this cycle, we'd like to enable basic sub-page compressed data
support for Android ecosystem (for vendors to try out 16k page size
with 4k-block images in their compatibility mode) as well as container
images (so that 4k-block images can be parsed on arm64 cloud servers
using 64k page size.)

In addition, there are several bugfixes and cleanups as usual.  All
commits have been in -next for a while and no potential merge conflict
is observed.

Thanks,
Gao Xiang
