The "industry standard" DDF format allows for a stripe/offset layout where
data is duplicated on different stripes. e.g.
A B C D
D A B C
E F G H
H E F G
(columns are drives, rows are stripes, LETTERS are chunks of data).
This is similar to raid10's 'far' mode, but not quite the same. So enhance
'far' mode with a 'far/offset' option which follows the layout of DDFs
stripe/offset.

If you misuse the device-mapper interface (or there's a bug in your userspace
tools) it's possible to end up with 'unlinked' mapped devices that cannot be
removed until you reboot (along with uninterruptible processes).
This patch prevents you from removing a device that is still open.
It introduces dm_lock_for_deletion() which is called when a device is about to
be removed to ensure that nothing has it open and nothing further can open it.
It uses a private open_count for this which also lets us remove one of the
problematic bdget_disk() calls elsewhere.

Persistent snapshots currently store a private copy of the chunk size.
Userspace also supplies the chunk size when loading a snapshot. Ensure
consistency by only storing the chunk_size in one place instead of two.
Currently the two sizes will differ if the chunk size supplied by userspace
does not match the chunk size an existing snapshot actually uses. Amongst
other problems, this causes an incorrect 'percentage full' to be reported.
The patch ensures consistency by only storing the chunk_size in one place,
removing it from struct pstore. Some initialisation is delayed until the
correct chunk_size is known. If read_header() discovers that the wrong chunk
size was supplied, the 'area' buffer (which the header already got read into)
is reinitialised to the correct size.

1 - backend is bound/bind backend to the VT layer
In addition, if any of the consoles are in KD_GRAPHICS mode, binding and

Thus the fbcon sysfs attributes, attach and detach, are also gone.

unregistered. If no registered driver remains, fbcon will unregister
itself from the console layer.
2. Replaced calls to give_up_console() with unregister_con_driver().
3. Still use take_over_console() instead of register_con_driver() to
maintain compatibility
4. Respect the parameter first_fb_vc and last_fb_vc instead of using 0 and
MAX_NR_CONSOLES - 1. These parameters are settable by the user.
5. When fbcon is completely unbound from the console layer, fbcon will
also release (iow, decrement module reference counts to zero) all fbdev
drivers. In other words, a bind or unbind request from the console layer
will propagate down to the framebuffer drivers.
6. If fbcon is not bound to the console, it will ignore all notifier
events (except driver registration and unregistration) and all sysfs
requests.

The framebuffer console is now able to dynamically bind and unbind from the VT
console layer. Due to the way the VT console layer works, the drivers
themselves decide when to bind or unbind. However, it was decided that
binding must be controlled, not by the drivers themselves, but by the VT
console layer. With this, dynamic binding is possible for all VT console
drivers, not just fbcon.
Thus, the VT console layer will impose the following to all VT console
drivers:
- all registered VT console drivers will be entered in a private list
- drivers can register themselves to the VT console layer, but they cannot
decide when to bind or unbind. (Exception: To maintain backwards
compatibility, take_over_console() will automatically bind the driver after
registration.)
- drivers can remove themselves from the list by unregistering from the VT
console layer. A prerequisite for unregistration is that the driver must not
be bound.
The following functions are new in the vt.c:
register_con_driver() - public function, this function adds the VT console
driver to an internal list maintained by the VT console
bind_con_driver() - private function, it binds the driver to the console
take_over_console() is changed to call register_con_driver() followed by a
bind_con_driver(). This is the only time drivers can decide when to bind to
the VT layer. This is to maintain backwards compatibility.
unbind_con_driver() - private function, it unbinds the driver from its
console. The vacated consoles will be taken over by the default boot console
driver.
unregister_con_driver() - public function, removes the driver from the
internal list maintained by the VT console. It will only succeed if the
driver is currently unbound.
con_is_bound() checks if the driver is currently bound or not
give_up_console() is just a wrapper to unregister_con_driver().
There are also 3 additional functions meant to be called only by the tty layer
for sysfs control:
vt_bind() - calls bind_con_driver()
vt_unbind() - calls unbind_con_driver()
vt_show_drivers() - shows the list of registered drivers
Most VT console drivers will continue to work as is, but might have problems
when unbinding or binding which should be fixable with minimal changes.

Add the ability to detach and attach the framebuffer console to and from the
vt layer. This is done by echo'ing any value to sysfs attributes located in
class/graphics/fbcon. The two attributes are:
attach - bind fbcon to the vt layer
detach - unbind fbcon from the vt layer
Once fbcon is detached from the vt layer, fbcon can be unloaded if compiled as
a module. This feature is quite useful for developers who work on the
framebuffer or console subsystem. This is also useful for users who want to
go to text mode or graphics mode without having to reboot.
Directly unloading the fbcon module is not possible because the vt layer
increments the module reference count for all bound consoles. Detaching fbcon
decrements the module reference count to zero so unloading becomes possible.
Detaching fbcon may interfere with X and/or DRM.
