I always thought of these tags as something more like a formality. In fact
this hasn't been my first patchset sent to the kernel e-mailing list.
Although all of the previous ones didn't involve someone else participating
in the changes development, except the reviewers of course. So I do aware
of all the tags mentioned in the doc. But as it turns out I didn't
fully understand their meaning. Main rule: most of the tags should not be
added without the permission, except more or less formal CC and Fixes ones.
Anyway thanks for the advice. Next time I'll be more careful with it.

Regards,
-Sergey
