CodingStyle

NBD Coding style.
=================

The following expresses my opinion of what C code should look like. I'm
not as strict as the Kernel maintainers on this one (NBD isn't even
remotely as large anyway), but code that does not follow these rules
needs to be updated so that it does, which is useless time wasted for
me. Therefore, it's appreciated if you would follow these rules.

Thanks.

* Use a tab width of 8 characters. You may use tab or 8 spaces as you
  please, it doesn't really matter to me.
* opening curly brackets occur on the same line as whatever they're
  curly brackets for, _in all cases_. This includes function
  definitions, if structures, loops, and so on; every code block appears
  like so:

int foo(int bar) {
  	...
}

* Variable declarations are separated from the rest of a function block
  by a line of whitespace. It's okay to assign a value to a variable
  when you're declaring it if you can do that on one line of code, but
  it must still be in the block of declarations at the top with a
  whiteline below.
* Variables are declared one on each line. So no

	int foo, bar;

  use

	int foo;
	int bar;

  instead.
* Try to fit everything in 80 columns. This goes especially for comment
  lines, but may be relaxed for function calls with 79 arguments, or so,
  if that's not feasible.
* If your function block is more than three or so screenfulls, there's a
  hint that you should break it up.

It is true that not all of the code currently follows these rules; but
that should not stop you from following them for new code, or from
cleaning up if you can (i.e., you have commit rights).
