Using mm.git or damon/next for DAMON patch baselines

[SeongJae Park <sj@kernel.org>]

Hello Sashiko team,


DAMON patches are usually based on a commit of damon/next [1] that based on
mm-new.  So the baseline commit that added by git on the patch should be
available on damon/next.  Or, mm-new should almost always the right choice for
the baseline.

But seems Sashiko is not aware of [2] that, and therefore sometimes fais
reviews at patch applying step.  Could we make Sashiko to use mm trees or the
baseline commit on damon/next tree?

I was thinking changes like below might work, but I don't know how to
read/write/test Rust code...  I also have no idea about how I can make Sashiko
to try finding the baseline commit from damon/next tree.  So just asking here.
