Hi,

Lately on many occasion it happened to me to touch the innodb code (in
particular related to virtual columns). And I modified the code only
in storage/xtradb. All tests passed.

Should I apply those changes to storage/innobase and storage
innodb_pligin? How can I check that the changes do not break anything?

I would appreciate if anybody clarifies this issue.

Regards,
Igor.
