Subject: [GIT PULL] erofs fixes for 5.15-rc3

Hi Linus,

Could you consider this pull request for 5.15-rc3?

2 bugfixes are included in order to fix the 4KiB blockmap chunk format
availability and a dangling pointer usage. There is also a trivial
cleanup to clarify compacted_2b if compacted_4b_initial > totalidx.

All commits have been in -next. This merges cleanly with master.

Gao Xiang
