* Commit the remaining part of PR14914:Poul-Henning Kamp1999-11-161-8/+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.

| | | | | | | | | | Moving this all from ufs wasn't a good move. At least the debugging routines depend on the file system. Cleaned up the LOCKF_DEBUG #includes. Notes: svn path=/head/; revision=22880

| | | | | | | | | | | | | | | | | | changes, so don't expect to be able to run the kernel as-is (very well) without the appropriate Lite/2 userland changes. The system boots and can mount UFS filesystems. Untested: ext2fs, msdosfs, NFS Known problems: Incorrect Berkeley ID strings in some files.

| | | | | | | | | | | cycles. While waiting there I added a lot of the extra ()'s I have, (I have never used LISP to any extent). So I compiled the kernel with -Wall and shut up a lot of "suggest you add ()'s", removed a bunch of unused var's and added a couple of declarations here and there. Having a lap-top is highly recommended. My kernel still runs, yell at me if you kernel breaks. Notes: svn path=/head/; revision=3098
