I also sometimes don't understand why they let me do it because they can but I understand there are a lot of patches for them to review.
Anyway, this is very simple to achieve it.
We just need to know commit-id on each patch.
We can use 'git log' for that.
For example, git shows patches like below when we type 'git log'.
$ git log
+++
commit commit-id1
Author Someone
Date Someday
Blur...blur..
commit commit-id2
Author Someone
Date Someday
Blur...blur..
...
+++
If we want to know diffs on commit-id1, we can do like below.
$ git diff commit-id1 commit-id2
In some cases, we can extract diffs to a file like below.
$ git diff commit-id1 commit-id2 > diff.txt
Hope this helps you.
