Sorry for the mistakes I made, I shall read the document about patches more carefully.
Here is the change logs:

Changes in v2:
- Display permissions information in sysfs insureds of debufs.
Changes in v3:
- Remove unnecessary null terminator after snprintf.

I didn’t mean to ignore it but I haven’t receive the response you described,
May you send the response to me again so I can do further revision as well as
change logs and resubmit the patch again?

Thanks for your patience
