This patch has already been committed, but for future reference code of 
this form:

LIST_FOR_EACH( cursor, list)
{
    TYPE list_entry = LIST_ENTRY( cursor, TYPE, entry );
    ...

Can be replaced by the following for IMHO, slightly more readable code:

LIST_FOR_EACH_ENTRY( list_entry, list, TYPE, entry)
{
    ...
