Some of what your have said above really needs to be in your commit
text. I've noticed that your commit text in general is not verbose
enough. You need to explain what doing better.
Also generally you want to organize similar sets of changes. So if you
doing a cleanup in preparation for another change then the cleanup
should go with the other change. In this case it's not clear that this
is actually a cleanup, so it would be much nicer to get that change
along with the one you've delayed .. Also the two Kconfig changes you've
sent indicate that your not organizing your changes properly, so I think
you need to take more time considering how to the organize patches.
Just so we're clear on this, any changes that you send me will go into
_permanent_ public history. This history will not disappear at some set
date, and we will not be rebasing out changes or squashing changes.
