So what is the rationale here. During mainlining our drivers we had to
remove all uses of 'typedef struct foo foo_t;'. The Linux CodingStyle
(chapter 5 Typedefs) is spending a number of lines explaining why.

So is spinlock_t an exception to this rule simply because the kernel
uses spinlock_t all over the place. Using Greg's favorite final email
remark:

Confused.
