So, # although the code looks a bit _funny_, I didn't want to refactor # or modify it beyond merely adding a fallthrough marking, which # might be the least disruptive way to fix this issue. # # [1] https://www.drdobbs.com/a-reusable-duff-device/184406208 # # Link: https://github.com/KSPP/linux/issues/115 # Signed-off-by: Gustavo A.
