1168ab0815 Fixed corruption of the "blocked" list in lf_setlock() when tsleep()
returns 0 after ptrace() attach and/or detach doesn't quite quite
deliver a signal.  Perhaps the process shouldn't be woken in this
case, but avoiding the problem is easy.

PR:		12247

Fixed a couple of places where mechanical fixing of compiler warnings
caused misspelling of NOLOCKF as NULL.

db72e05829 Fix a freelist trashing under following confitions:
- first program lock a region in a file,
- second program wait on the lock,
- first program extend the region,
- second program interrupted by a signal.

3f2076daf5 Make the debug options new-style.
This also zaps a DPT option from lint; it wasn't referenced from
anywhere.

1cd52ec333 Don't include <sys/lock.h> in headers when only `struct simplelock' is
required.  Fixed everything that depended on the pollution.

a1c995b626 Last major round (Unless Bruce thinks of somthing :-) of malloc changes.
Distribute all but the most fundamental malloc types.  This time I also
remembered the trick to making things static:  Put "static" in front of
them.

A couple of finer points by:	bde

ready for it yet.

a8687b6dcd Added some ufs #includes so that this compiles with option LOCKF_DEBUG.
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.

996c772f58 This is the kernel Lite/2 commit. There are some requisite userland
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.
		Mount_std mounts will not work until the getfsent
		library routine is changed.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

675526e892 Delete bogus inconsistency check that could cause a gratuitous panic. I
had added this years ago when I didn't understand all the subtilties of
the flock code.

a88bd8aae4 Fixed arg checking in if_advlock(). Invalid args were accepted in an
optimized case.  Preposterous lengths weren't checked for.

b71fec07db Eliminated nested include of <sys/unistd.h> in <sys/file.h> in the kernel.
Include it directly in the few places where it is used.

Reduced some #includes of <sys/file.h> to #includes of <sys/fcntl.h> or
nothing.

bb56ec4a05 While in the real world, I had a bad case of being swapped out for a lot of
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.

92dc7331c9 Made lockf advisory locking code generic (rather than ufs specific), and
use it in NFS. This is required both for diskless support and for POSIX
compliance. Note: the support in NFS is only for the local node.
