Hi, Since v5.10 is an LTS release, I'm wondering should we backport write time tree-checker feature to v5.10? There are already some reports of runtime memory bitflip get written to disk and causing problems. Unfortunately write-time tree-checker is only introduced in v5.11, one version late. Considering how many bitflips write-time tree-checker has caught (and prevented corrupted data reaching disk), I think it's definitely worthy to backport it to an LTS kernel. Or is there any special requirement for LTS kernel to reject certain features? Thanks, Qu
