-		3.1:  Spaces
-
-Linux kernel style for use of spaces depends (mostly) on
-function-versus-keyword usage.  Use a space after (most) keywords.  The
-notable exceptions are sizeof, typeof, alignof, and __attribute__, which look
-somewhat like functions (and are usually used with parentheses in Linux,
-although they are not required in the language, as in: "sizeof info" after
-"struct fileinfo info;" is declared).
-
-So use a space after these keywords:
-	if, switch, case, for, do, while
-but not with sizeof, typeof, alignof, or __attribute__.  E.g.,
-	s = sizeof(struct file);
-
-Do not add spaces around (inside) parenthesized expressions.  This example is
-*bad*:
-
-	s = sizeof( struct file );
-
-When declaring pointer data or a function that returns a pointer type, the
-preferred use of '*' is adjacent to the data name or function name and not
-adjacent to the type name.  Examples:
-
-	char *linux_banner;
-	unsigned long long memparse(char *ptr, char **retptr);
-	char *match_strdup(substring_t *s);
-
-Use one space around (on each side of) most binary and ternary operators,
-such as any of these:
-
-	=  +  -  <  >  *  /  %  |  &  ^  <=  >=  ==  !=  ?  :
-
-but no space after unary operators:
-	&  *  +  -  ~  !  sizeof  typeof  alignof  __attribute__  defined
-
-no space before the postfix increment & decrement unary operators:
-	++  --
-
-no space after the prefix increment & decrement unary operators:
-	++  --
-
-and no space around the '.' and "->" structure member operators.
