[GIT PULL] erofs updates for 6.13-rc1

[Gao Xiang]

Hi Linus,

Could you consider this pull request for 6.13-rc1?

There is no outstanding feature for this cycle.  The most useful changes
are SEEK_{DATA,HOLE} support and some decompression micro-optimization.
Other than those, there are some bugfixes and cleanups as usual.

All commits have been in -next for a while and no potential merge
conflict is observed.

Thanks,
Gao Xiang
