Linus, I know I run a risk of being not the first person to ask this,
but anyway.

I've got a patch for my project to fix parsing of kernel version which
has only two numbers. Basically,

- scanf(ver, "%u.%u.%u", &a, &b, &c)
+ sscanf(ver, "%u.%u", &a, &b)

I can take it, but it made me thinking: how many other projects
will be similarly affected? Must be hundreds, even thousands.

I propose to still use three digits. I mean, if you want to use
3.0, 3.1, 3.2 numbering for your releases and leave third digit
for stable series, just number them 3.0.0, 3.1.0, 3.2.0 instead.

This way, many userspace projects will need less patching
in order to work with 3.x. In many cases, they can
avoid patching altogether.
