81bca6ddae Clustered read and write are switched at mount-option level.
1. Clustered I/O is switched by the MNT_NOCLUSTERR and MNT_NOCLUSTERW
   bits of the mnt_flag.  The sysctl variables, vfs.foo.doclusterread
   and vfs.foo.doclusterwrite are deleted.  Only mount option can
   control clustered I/O from userland.
2. When foofs_mount mounts block device, foofs_mount checks D_CLUSTERR
   and D_CLUSTERW bits of the d_flags member in the block device switch
   table.  If D_NOCLUSTERR / D_NOCLUSTERW are set, MNT_NOCLUSTERR /
   MNT_NOCLUSTERW bits will be set.  In this case, MNT_NOCLUSTERR and
   MNT_NOCLUSTERW cannot be cleared from userland.
3. Vnode driver disables both clustered read and write.
4. Union filesystem disables clutered write.

99448ed11d Change the M_NAMEI allocations to use the zone allocator. This change
plus the previous changes to use the zone allocator decrease the useage
of malloc by half.  The Zone allocator will be upgradeable to be able
to use per CPU-pools, and has more intelligent usage of SPLs.  Additionally,
it has reasonable stats gathering capabilities, while making most calls
inline.

a9320ff3bd Revised fix for locking violation when unionfs calls vput with
UN_KLOCK flag.

When UN_KLOCK is set, VOP_UNLOCK should keep uppervp locked and clear
UN_ULOCK flag.  To do this, when UN_KLOCK is set, (1) union_unlock
clears UN_ULOCK and does not clear UN_KLOCK, (2) union_lock() does not
access uppervp and does not clear UN_KLOCK, and (3) callers of
vput/VOP_UNLOCK should clear UN_KLOCK.  For example, vput becomes:

	SETKLOCK(union_node);
	vput(vnode);
	CLEARKLOCK(union_node);

where SETKLOCK macro sets UN_KLOCK and CLEARKLOCK macro clears
UN_KLOCK.

928e13b6a1 Do not clear UN_ULOCK in certain case.
Our vput calls vm_object_deallocate() --> vm_object_terminate().  The
vm_object_terminate() calls vn_lock(), since UN_LOCKED has been
already cleared in union_unlock().  Then, union_lock locks upper vnode
when UN_ULOCK is not set.  The upper vnode is not unlocked when
UN_KLOCK is set in union_unlock(), thus, union_lock tries to lock
locked vnode and we get panic.

9095719e2b Quick-hack to avoid `lock against myself' panic. It is not the real
fix!

The ufs_link() assumes that vnode is not unlocked and tries to lock it
in certain case.  Because union_link calls VOP_LINK after locking vnode,
vn_lock in ufs_link causes above panic.

Currently, I don't know the real fix for a locking violation in
union_link, but I think it is important to avoid panic.

A vnode is unlocked before calling VOP_LINK and is locked after it if
the vnode is not union fs.  Even though panic went away, the process
that access the union fs in which link was made will hang-up.

Hang-up can be easily reproduced by following operation:

	mount -t union a b
	cd b
	ln foo bar
	ls

6db918e371 Fix `lockmgr: locking against myself' panic by multi union mount of
same directory pair.

If we do:
    mount -t union a b
    mount -t union a b
then, (1) namei tries to lock fs which has been already locked by
first union mount and (2) union_root() tries to lock locked fs.  To
avoid first deadlock condition, unlock vnode if lowerrootvp is union
node, and to avoid second case, union_mount returns EDEADLK when multi
union mount is detected.

acdbeb6b1c changes to make devfs more 'normal'
also fixes a bug I've been chasing for a LONG TIME,
due to the fact that spec_bwrite is a NOP and I didn't realise it..

old symptom:
mount -t devfs devfs /mnt
mount /mnt/wd0e /mnt/mnt2
umount /mnt2 <process hangs>

there are some pretty large structural differences internal to devfs
but outwards it should look the same.
I have not yet tested extensively but will do so and fix 3 warnings tomorrow.

6476c0d204 Even though this looks like it, this is not a complex code change.
The interface into the "VMIO" system has changed to be more consistant
and robust.  Essentially, it is now no longer necessary to call vn_open
to get merged VM/Buffer cache operation, and exceptional conditions
such as merged operation of VBLK devices is simpler and more correct.

This code corrects a potentially large set of problems including the
problems with ktrace output and loaded systems, file create/deletes,
etc.

Most of the changes to NFS are cosmetic and name changes, eliminating
a layer of subroutine calls.  The direct calls to vput/vrele have
been re-instituted for better cross platform compatibility.

f863805df0 This time, really make the procfs work when reading stuff from the UPAGES.
This is a really ugly bandaid on the problem, but it works well enough for
'ps -u' to start working again.  The problem was caused by the user
address space shrinking by a little bit and the UPAGES being "cast off" to
become a seperate entity rather than being at the top of the process's
vmspace.  That optimization was part of John's most recent VM speedups.

Now, rather than decoding the VM space, it merely ensures the pages are
in core and accesses them the same way the ptrace(PT_READ_U..) code does,
ie: off the p->p_addr pointer.

0cc7521383 Major fixes for procfs..
Implement a "variable" directory structure. Files that do not make
sense for the given process do not "appear" and cannot be opened.
For example, "system" processes do not have "file", "regs" or "fpregs",
because they do not have a user area.

"attempt" to fill in the user area of a given process when it is being
accessed via /proc/pid/mem (the user struct is just after
VM_MAXUSER_ADDRESS in the process address space.)

Dont do IO to the U area while it's swapped, hold it in place if possible.

Lock off access to the "ctl" file if it's done a setuid like the other
pseudo-files in there.

87f6c6625d Pass 3 of the great devsw changes
most devsw referenced functions are now static, as they are
in the same file as their devsw structure. I've also added DEVFS
support for nearly every device in the system, however
many of the devices have 'incorrect' names under DEVFS
because I couldn't quickly work out the correct naming conventions.
(but devfs won't be coming on line for a month or so anyhow so that doesn't
matter)

If you "OWN" a device which would normally have an entry in /dev
then search for the devfs_add_devsw() entries and munge to make them right..
check out similar devices to see what I might have done in them in you
can't see what's going on..
for a laugh compare conf.c conf.h defore and after... :)
I have not doen DEVFS entries for any DISKSLICE devices yet as that will be
a much more complicated job.. (pass 5 :)

pass 4 will be to make the devsw tables of type (cdevsw * )
rather than (cdevsw)
seems to work here..
complaints to the usual places.. :)

adb2dc299a #ifdef out nearly the entire file of conf.c when JREMOD is defined
add a few safety checks in specfs because
now it's possible to get entries in [cd]devsw[] which are ALL NULL
so it's better to discover this BEFORE jumping into the d_open() entry..

more check to come later.. this getsthe code to the stage where I
can start testing it, even if I haven't caught every little error case...
I guess I'll find them quick enough..

53ac6efbd8 OK, that's it..
That's EVERY SINGLE driver that has an entry in conf.c..
my next trick will be to define cdevsw[] and bdevsw[]
as empty arrays and remove all those DAMNED defines as well..

Each of these drivers has a SYSINIT linker set entry
that comes in very early.. and asks teh driver to add it's own
entry to the two devsw[] tables.

some slight reworking of the commits from yesterday (added the SYSINIT
stuff and some usually wrong but token DEVFS entries to all these
devices.

BTW does anyone know where the 'ata' entries in conf.c actually reside?
seems we don't actually have a 'ataopen() etc...

If you want to add a new device in conf.c
please  make sure I know
so I can keep it up to date too..

as before, this is all dependent on #if defined(JREMOD)
(and #ifdef DEVFS in parts)

f57e65478d Introduced a type `vop_t' for vnode operation functions and used
it 1138 times (:-() in casts and a few more times in declarations.
This change is null for the i386.

The type has to be `typedef int vop_t(void *)' and not `typedef
int vop_t()' because `gcc -Wstrict-prototypes' warns about the
latter.  Since vnode op functions are called with args of different
(struct pointer) types, neither of these function types is any use
for type checking of the arg, so it would be preferable not to use
the complete function type, especially since using the complete
type requires adding 1138 casts to avoid compiler warnings and
another 40+ casts to reverse the function pointer conversions before
calling the functions.

159a024357 Make a lot of private stuff static.
Should anybody out there wonder about this vendetta against global
variables, it is basically to make it more visible what our interfaces
in the kernel really are.
I'm almost convinced we should have a
	#define PUBLIC /* public interface */
and use it in the #includes...

56c3ab883e find some way of letting a node know where in its parent's directory structure
it was referenced from.. stops a rather annoying panic, but
introduces a rather interesting but "I can live with it" bug
`ln a b ; mv a b; echo ?`
returns a rather than b..
I know why but I need to think of the 'correct' answer. at least this is 'safe'

564643c636 More hacking on devfs..
I can  now do an mv on devices and directories in devfs
This was the hardest part.. link, delete and symlink will follow in
short order.
This code works but has definitly got vnode locking problems
I am electing to get the structure of it working before
spending too much time on the vnode confusion
so it's probably not reliable at the moment..
never-the less it looks good.

ab746f65c1 Suggested by: :) bde of course
added prototypes for every function and
put (void *) as the args to the vop array definitions.

can now compile with:
CWARNFLAGS?=    -W -Wreturn-type -Wcomment -Wredundant-decls -Wimplicit \
                -Wnested-externs -Wstrict-prototypes -Wmissing-prototypes \
                -Winline -Wstrict-prototypes
and only get errors for files external to this module:
namely
./vnode_if.h
../../sys/vnode.h
../../sys/buf.h
../../miscfs/specfs/specdev.h

8af5d536ff devfs changes..
changes to allow devices that don't probe (e.g. /dev/mem)
to create devfs entries
this required giving 'configure' its own SYSINIT entry
so we could duck in just before it with a DEVFS init
and some device inits..
my devfs now looks like:
./misc
./misc/speaker
./misc/mem
./misc/kmem
./misc/null
./misc/zero
./misc/io
./misc/console
./misc/pcaudio
./misc/pcaudioctl
./disks
./disks/rfloppy
./disks/rfloppy/fd0.1440
./disks/rfloppy/fd1.1200
./disks/floppy
./disks/floppy/fd0.1440
./disks/floppy/fd1.1200
also some sligt cleanups.. DEVFS needs a lot of work
but I'm getting back to it..
