What is the whole process of cooking git as a maintainer?

["Ping Yin" <pkufranky@gmail.com>]

I have scanned the manual and found a 'Linux subsystem maintainer'
example. However, that's a little brief and i wonder a more real
example. I think an example of how to cook git as a maintainer is
better.

Junio , could you please share the whole process of cooking among pu,
next and master? Or, can i find this in the mail list archive?

For example:
In which branch the test is performed?
How to rewind pu?
How to merge a subset of changes from pu to next, and from next to master?
