[GIT PULL] erofs updates for 6.11-rc1

[Gao Xiang]

Hi Linus,

Could you consider this pull request for 6.11-rc1?

No outstanding new features have landed for this cycle so far.

There are patches addressing folio conversions for compressed inodes:
While large folio support for compressed data could work now, it remains
disabled since the stress test could hang due to page migration in a few
hours after enabling it.  I need more time to investigate further before
enabling this feature.

Additionally, there are also some patches to clean up stream
decompressors and tracepoints for simplicity.

All commits have been tested and no potential merge conflict is
observed.

Thanks,
Gao Xiang
