53d745bc7c Actually make use of the md_version field of 'struct mdio'. In order
not to needlessly break compatibility, decrement MDIOVERSION to 0.

26a0ee75c6 Introduce a force option, MD_FORCE, that instructs the driver to
bypass some extra anti-foot-shooting measures.  Currently, its only
effect is to allow detaching a device while it's still open (e.g.,
mounted).  This is useful for testing how the system reacts to a disk
suddenly going away, which can happen with some removeable media.

At this point, the force option is only checked on detach, so it
would've been possible to allow the option to be passed with the
MDIOCDETACH operation.  This was not done to allow the possibility of
having the force flag influence other tests in the future, which may
not necessarily deal with detaching the device.

c894b25a2f Constify mdmaybeload(), add a prototype for usage(), and get rid of a
sizeof(int) == sizeof(long) assumption; clamp down with WARNS=2.

2885b42173 Fail if -s isn't specified for an MD_MALLOC or MD_SWAP disk; the
driver itself obviously won't configure such a disk, but the error
returned (EDOM) is more cryptic to the average user than it should be.

Also assert that the argument to -u is in fact a valid unit; don't
just accept any string to mean 0.

ed23a390c2 In the absence of explicit `-t type'' option assume that `-f file''
implies ``-t vnode''.

83da2a90ae 1) If mdconfig isn't given an action argument, it assumes detach.
2) Running `mdconfig -l` without any attached devices results in
mdconfig printing "md0" to standard output.

3f6f92161c Remove "autounit" from settable options, it's the default unless you
specify -u.

Implement "-l" option to mdconfig which can list one or all md devices.

3b42f2f3bb Duh, the version of mdconfig.c I committed came from the wrong machine.
Commit the right version, but without the -b option which is too evil
for the present.

Remove -b and preload from the manpage as well.

e06b153abe Add padding space and a version number to the md_ioctl structre for future
extension.

Add ability to create a preload disk giving an address and a length
(suggested by imp)

Fix bug relating to very small md(4) devices.

Update md.c copyright to reflect the status of code copied from vn.c.

8f8def9e2c This is the first snapshot of the new all-singing-and-dancing md(4).
Using the mdconfig(8) program you can now configure memory disks
on malloc(9), swap or a file/vnode.  preloaded md disks also work
as usual.

70d586c091 Preliminary scaffolding for the new integrated vn+md device driver.
I decided to work on the md(4) driver and integrate the vn(4)
functionality into it mainly based on the name being more suitable.
Ideally 'vd' as in "virtual disk" would probably be the most logical
but our sound-master pointed out that this would cause uncontrollable
fits of giggles in the brits.  Another complication would the needed
changes to the ramdisk boot/root functionality.

The vn driver will stay around for some time after I complete this
merge for transition reasons, and I'll make it whine to people that
they should migrate to the md(4) driver for some time before it
dies.

The kernel part of the new md(4) driver will be committed after more
testing.
