A bit of quilt

Hi,
As I know quilt is used by maintainers. But kernel source code is
maintained in git repo. So I want to know how git and quilt work
together.

In mutt I have seen that a mail sent by Mr. GregKH has  quilt mail as user
agent and git-send-email as x-mailer. It means he is using
git-send-email as a backend for quilt mail.

Last but not least, I think if a developer starts using quilt to
maintain his diferent versions of a patch, it will ease a maintainer
job.

Regards,
Amit Kumar
