Wouldn't it be better to cast "unsigned long" in the call to atomic_set()?
Why should it better ?
Maybe not better, but at least it is consistent with the type of random_seqno, which is unsigned long. I know the two types are identical, but nevertheless, I like to use the same type of type :)
You lost me somewhere. Yes, random_seqno is unsigned long. If we wanted to store unsigned long we would not need a cast. However, in my kernel the second argument for atomic_set() is "int" and not "unsigned long" which why we have a cast there.
