Do you remember the reason? I found the oposite to be ture, I actually 
started with the do { } while(0) construct but it failed in certain 
situations so I wrapped it with ({ }) and then later removed
the now useless do { } while(0).

By the way printk_once which is defined a few lines further down in
kernel.h also uses ({ }).

Anyway the next version of my patch will no longer need it.
