[GIT PULL] erofs update for 5.10-rc1

[Gao Xiang]

Hi Linus,

Could you consider this pull request for 5.10-rc1?

This cycle addresses a reported permission issue with overlay
due to a duplicated permission check for "trusted." xattrs.
Also, a REQ_RAHEAD flag is added now to all readahead requests
in order to trace readahead I/Os. The others are random cleanups.

All commits have been tested and have been in linux-next as well.
This merges cleanly with master.

Thanks,
Gao Xiang
