My gosh, this is done already in list_for_each*()
No, list_for_each_entry does NOT check if the list is empty or if the
first entry is NULL.
NULL is never valid for a list. It does however check for an empty list
It does it implicitely in the test part of the for () statement,
checking if the next pointer points back to the head.
Thanks Ben. My mistake on this one; I misread the macro. I will remove
the check in v9... going to wait a little for any further comments now.
Thanks,
Eddie
Cheers,
Ben.
