734e78dfcb Disallow attaching preloaded memory disks via ioctl. 
- The feature is dangerous because the kernel code didn't check
  validity of the memory address provided from user space.
- It seems that mdconfig(8) never really supported attaching preloaded
  memory disks.
- Preloaded memory disks are automatically attached during md(4)
  initialization. Thus there shouldn't be much use for the feature.

c313f09bfb When using files as backing stores for devices, and the user has requested the 
device be created read+write, check to see if the backing store is read only
through the use of the access(2) system call. If this check fails returning
EACCES, EPERM or EROFS then gracefully downgrade the access to read only. Also
print a warning message to stderr, informing the user that the access mode
they requested is not available.

This behavior used to be handled by md(4) but was changed in revision 1.154

7a6b2b6429 Fix a long-standing deadlock issue with vnode backed md(4) devices: 
On vnode backed md(4) devices over a certain, currently undetermined
size relative to the buffer cache our "lemming-syncer" can provoke
a buffer starvation which puts the md thread to sleep on wdrain.

This generally tends to grind the entire system to a stop because the
event that is supposed to wake up the thread will not happen until a fair
bit of the piled up I/O requests in the system finish, and since a lot
of those are on a md(4) vnode backed device which is currently waiting
on wdrain until a fair amount of the piled up ... you get the picture.

The cure is to issue all VOP_WRITES on the vnode backing the device
with IO_SYNC.

In addition to more closely emulating a real disk device with a
non-lying write-cache, this makes the writes exempt from rate-limited
(there to avoid starving the buffer cache) and consequently prevents
the deadlock.

Unfortunately performance takes a hit.

Add "async" option to give people who know what they are doing the
old behaviour.

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.

e10469fef8 Make md(4) and mdconfig(8) take over the role of vn(4) and vnconfig(8) 
entirely as previously advertised.

md(4) adopted all assets of vn(4) some time back and has proper devfs
