Most of the conventions are directly from 
/usr/src/linux/Documentation/CodingStyle.  The blank line before if 
requirement is more of an internal convention.  Just follow what the existing 
code does and you'll be alright.

However, in general the if must be preceded by a blank line, UNLESS the if is 
nested and not preceded by an expression or variable declaration.  The 
following form is also acceptable:

foo = malloc();
if (foo == NULL)
	return;

If in doubt, check what the existing code does.  The maintainer has the final 
say.
