Subject: [GIT PULL] erofs updates for 6.1-rc1
Date: Mon, 3 Oct 2022 19:13:43 +0800	[thread overview]
Message-ID: <YzrD50lgln3c9zEf@debian> (raw)

Hi Linus,

Could you consider this pull request for 6.1-rc1?

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.

Besides, 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.

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

Gao Xiang
