Let me put this straight, quoting the Kernel Documentation/CodingStyle:

 75                 Chapter 2: Breaking long lines and strings

 76

 77 Coding style is all about readability and maintainability using commonly

 78 available tools.

 79

 80 The limit on the length of lines is 80 columns and this is a strongly

 81 preferred limit.

 82

 83 Statements longer than 80 columns will be broken into sensible
chunks, unless

 84 exceeding 80 columns significantly increases readability and does not hide

 85 information. Descendants are always substantially shorter than the
parent and

 86 are placed substantially to the right. The same applies to function headers

 87 with a long argument list. However, never break user-visible strings such as

 88 printk messages, because that breaks the ability to grep for them."
