[GIT PULL] erofs updates for 6.17-rc1

[Gao Xiang]

Hi Linus,

Could you consider this pull request for 6.17-rc1?

In this cycle, metadata compression is now supported due to user
requests [1].  It can be useful for embedded use cases or archiving
a large number of small files.

Additionally, readdir performance has been improved by enabling
readahead (note that it was already common practice for ext3/4 non-dx
and f2fs directories).  We may consider further improvements later to
align with ext4's s_inode_readahead_blks behavior for slow devices too.

The remaining commits are minor.  All commits have been in -next and no
potential merge conflict is observed.

Thanks,
Gao Xiang
