[GIT PULL] erofs updates for 6.19-rc1

[Gao Xiang]

Hi Linus,

Could you consider this pull request for 6.19-rc1?

There is still no outstanding feature for this cycle
since page cache sharing feature is still under review.

All commits have been in -next except for the obvious
license change one and no potential merge conflict is
observed.

Thanks,
Gao Xiang
