Subject: [GIT PULL] erofs fixes for 6.1-rc2

(sorry, forgot to send to related mailing lists... resend now)

Hi Linus,

Could you consider these fixes for 6.1-rc2?

There are some bugs reported these days and the following patches
address them.

Some issues looks trivial but the compressed data deduplication one
can only be reproduced with the stress test for almost two weeks.

Anyway, I think all of them needs to be fixed immediately and details
are shown as below.  All commits have been in linux-next and no merge
conflicts.

Thanks,
Gao Xiang
