[dm-devel] [Question] How to make a patch?

[Akira Hayakawa]

Hi,

I am going to send you a patch of dm-lc on this weekend.
But, I am wondering how I make a patch.

1. What tree do I need to use?
2. Where should I make a patch on?

I git-cloned both linux-next and linux-dm.
Which one should I use?

linux-dm seems to have a tag dm-3.11-changes.
Should I make patch on this point?

Sorry for too basic question,
Akira
