Subject: [GIT PULL] erofs fixes for 5.16-rc3

Hi Linus,

Could you consider this pull request for 5.16-rc3?

This fixes a regression introduced by the XArray convention
which can cause ABBA deadlock in the low memory scenarios.

Jianhua Hao also reported this issue recently. All commits
have been in -next and no merge conflicts.

Many thanks!
Gao Xiang
