* Commit the remaining part of PR14914:phk1999-11-161-8/+8
| | | | | | | | | | | Alot of the code in sys/kern directly accesses the *Q_HEAD and *Q_ENTRY structures for list operations. This patch makes all list operations in sys/kern use the queue(3) macros, rather than directly accessing the *Q_{HEAD,ENTRY} structures.
