That one is nice enough, it's the !! that Linus came out fairly
strongly against though not sure I can find the particular email.
That one is a fairly kernel specific idiom that I'll be honest I've
rarely seen elsewhere ;) I remember wincing at the thread
on this as it was an idiom I personally rather liked.
In cases where it doesn't matter because foo doesn't need to 1 or
0 then what you have is nice and clean.
I can't say it's one I care that much about, but I am happy if code
that happens to be under cleanup anyway has this little bit made
the 'preferred style'. There is something to said for consistency.
