I haven't seen any bugs caused by lack of type safety with "!foo"...
I prefer !foo because it is more common in the kernel and I think it's
easier to read but I don't feel strongly about this.
I kind of hate "if (foo != NULL) though, because it's a double negative.
But I really hate when people start adding the "!= 0" on to all their
conditions.
if (frob() != 0)
Also:
if (a + b != 0)
People do this all the time instead of "if (a || b)" and I don't know
why...

dan carpenter
