[PATCH] VT binding: Add sysfs control to the VT layer
Add sysfs control to the VT layer. A new sysfs class, 'vtconsole', and class
devices 'vtcon[n]' are added. Each class device file has the following
attributes:
/sys/class/vtconsole/vtcon[n]/name - read-only attribute showing the
name of the current backend
/sys/class/vtconsole/vtcon[n]/bind - read/write attribute
where: 0 - backend is unbound/unbind backend from the VT layer
1 - backend is bound/bind backend to the VT layer
In addition, if any of the consoles are in KD_GRAPHICS mode, binding and
unbinding will not succeed. KD_GRAPHICS mode usually indicates that the
underlying console hardware is used for other purposes other than displaying
text (ie X). This feature should prevent binding/unbinding from interfering
with a graphics application using the VT.
