| |
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
