Hi Horatiu,

Thank you for review comments.
In vim editor, set the textwidth as 75. Due to this, after 75 charecters of
the line, string placed in next line.

Please find the screenshot of column marker with textwidth.
I will fix it and repost the patch again.

Fixes tag correction was suggested by Jakub in V2 patch.

The fixes tag should not spread over multiple lines. Also you have extra
spaces between External and Timestamp which doesn't appear in the actual
commit.

Also you have an empty line between Fixes and Reviewed-by tags.

I am not sure that Jakub gave his Reviewed-by, but maybe I have missed
that.

Does not mean I reviewed the patch, only add review tags if someone
explicitly sent them to you.
