i'm sure i'm misreading something, but when i look at the macro
definition of "__list_for_each" in list.h:
#define __list_for_each(pos, head) \
for (pos = (head)->next; pos != (head); pos = pos->next)
i could swear that this traversal will visit each node in the list
except for the initial head element.
look closely: given a starting address of "head", the
initialization starts things off at (head)->next, and continues
traversing as long as pos != head. so wouldn't this traversal end up
*not* visiting the list element addressed by "head" itself? or is
that what it's supposed to do?
