Hi Linus,

Sorry, could you consider pull this tag "erofs-for-6.8-rc1-2" instead of
the previous email one since commit de9bced860d4 ("erofs: fix
inconsistent per-file compression format") was just found
problematically on some LZMA images.

Since the previous email hasn't been processed, it'd be better to drop
this problematic patch directly and submit a new fix later instead of
fixing a fix commit.

The description for this pull request is still as below:

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.

Sorry again,
Gao Xiang
