Documentation/SubmittingPatches says:
- Some clever tricks, like using the !! operator with arithmetic
constructs, can be extremely confusing to others.
If !!ptr is a **more established way** to then why should it confuse

!!ptr was stated as an "exception-rule" where ptr is a pointer (possibly
NULL). That makes
me wonder in what case is it "confusing" at all?
