First, there's the USB side (and other I'm sure less visible cases) where this does change behavior a bit. But second, and harder to deal with, is that this totally breaks all of our test/py code (make tests hangs) and I haven't come up with a good fix. I think some of these changes can certainly be brought in. -- Tom
- the logic is opposite - currently, assert() is compiled only when DEBUG is defined Coccinelle can easily convert assert() to BUG_ON(). A problem is it would grow the image size. In v2, I introduced a new CONFIG option to allow to disable it. In v3, it is default 'y'. I disabled it only for openrd boards.
