Don't do it like this...  The original code is better so, I guess, lets
leave it as is.  There are two accepted ways to start a function in the
kernel:

ONE:
static type
function_name(paramenters)

TWO
static type function_name(paramenters)

Either option will let you grep for the names of the functions:

	egrep "^[a-zA-Z]" dir/file.c | grep '('
