Subject: Re: [PATCH v8 net-next 1/3] filter: add Extended BPF interpreter and converter

Why not for variables? It makes a lot of sense of nothing else to avoid the confusion that invariably happens when someone decides to introduce the value 2 or -1 to an existing variable (and yes, thus has happened a number of times.)

Not to mention they take a single byte rather than four for an int if stored in memory.
