[GIT PULL] erofs updates for 6.15-rc1

[Gao Xiang <xiang@kernel.org>]

Hi Linus,

Could you consider this pull request for 6.15-rc1?

In this cycle, EROFS 48-bit block addressing is available to support
massive datasets for model training and other large data archive use
cases.

In addition, byte-oriented encoded extents have been supported to
reduce metadata sizes when using large configurations as well as to
improve Zstd compression speed.

There are some bugfixes and cleanups as usual.  All commits have been
in -next for a while and no potential merge conflicts is observed.

Thanks,
Gao Xiang
