Subject: [GIT PULL] erofs fixes for 6.16-rc6

Hi Linus,

Could you consider these fixes for 6.16-rc6?

One patch fixes a cache aliasing issue by adding missing
flush_dcache_folio(), which causes execution failures on some arm32
setups.

Another patch fixes some large compressed fragments, which could be
generated by -Eall-fragments option (but should be rare) and was
rejected by mistake due to an on-disk hardening commit.

The remaining ones are small fixes as shown below.

Thanks,
Gao Xiang
