Linus Torvalds：

1.制表符8位。 

2.大括号：

if (x is true) {
		we do y
	}

int function(int x)
	{
		body of function
	}
do {
		body of do-loop
	} while (condition);

if (x == y) {
		..
	} else if (x > y) {
		...
	} else {
		....
	}
		 

3.变量名：全局要用有意义的（count_active_users()" or similar, you should _not_ call it "cntusr()". 

 局部变量要简短比如（i,tmp)

4 .函数：

函数应该简短干练。且局部变量应该少于十个。 

5.注释：Generally, you want your comments to tell WHAT your code does, not HOW. 
Also, try to avoid putting comments inside a function body ，
put the comments at the head
of the function, telling people what it does, and possibly WHY it does
it.
