It is particularly irritating during bisection. Nice series! Acked-by: Arnd Bergmann There are a number of files that we leave behind after a make clean, and I also wondered if we could remove some more of them, but I couldn't easily figure out which of them were left intentionally. The asm-generic wrappers certainly are not there for a good reason, and it's good to see them gone. Arnd
