How to add the Signed-off-by field in the git patch

When you commit, just use:

git commit -s

or

git commit --signoff

Or you can just write at the end of the commit message, on a line by itself separated by a blank line from the body of the commit:

Signed-off-by: Your Name <[email protected]>

If you already have the commit, use git commit -s --amend to add the above signoff line.

Or, if you are going to be sending this as a patch or patch series, you can use git format-patch -s or --signoff to add the signoff to the patch itself, without modifying the commit.

use git commit -s --amend for amending with the last commit or use git commit -s to current ongoing commit. It will add Signed-off-by: YourGitConfigName <YourGitConfigEmail> ad the end of the commit message.
