But frankly, I can't give this priority for a while :/ SDHI is used on a lot of platforms, even on different architectures. Regression testing will be a big one here. > That said, I am worried that it might be harder to move away from > tasklets beyond $subject series, for tmio/sdhi, but I might be wrong? > So, I am wondering if it perhaps would be better to make that > modernization/conversion as the first step instead? As said above, I can't do this in the foreseeable future. However, this series fixes an issue we see. So, my vote goes for applying this now. Even if it costs some extra cycles on the tasklet-removal-work. D'accord?
