Pull erofs updates from Gao Xiang:
"In this cycle, for container use cases, fscache-based shared domain is
introduced [1] so that data blobs in the same domain will be storage
deduplicated and it will also be used for page cache sharing later.
Also, a special packed inode is now introduced to record inode
fragments which keep the tail part of files by Yue Hu [2]. You can
keep arbitary length or (at will) the whole file as a fragment and
then fragments can be optionally compressed in the packed inode
together and even deduplicated for smaller image sizes.
In addition to that, global compressed data deduplication by sharing
partial-referenced pclusters is also supported in this cycle.
Summary:
- Introduce fscache-based domain to share blobs between images
- Support recording fragments in a special packed inode
- Support partial-referenced pclusters for global compressed data
deduplication
- Fix an order >= MAX_ORDER warning due to crafted negative i_size
- Several cleanups"
