Tiny style issue; Documentation/CodingStyle says:

"Do not unnecessarily use braces where a single statement will do.

if (condition)
        action();

This does not apply if one branch of a conditional statement is a single
statement. Use braces in both branches.

if (condition) {
        do_this();
        do_that();
} else {
        otherwise();
}
"

So, in the above, you should have curly braces around both the 'if' and 
'else' parts since one of them is more than one statement.
