Re: [PATCH 0/2] btrfs: add error injection support for checksum verification

[Song Chen]

Dear Maintainers and Reviewers,

This is friendly ping on this patchset.

The motive is rational and the implementation is simple and clear, 
what's more, no impact to any other function. I would appreciate it if 
you could have a look and leave comments.

Best regards,

Song
