Ok, here is the next round of driverfs updates.
Short summary:
- move device and driver interface to driverfs into drivers/base/fs/*.c
- Implement bus_{create,remove}_file and driver_{create,remove}_file to
give people an interface to create files those object types in their
respective directories.
driver_{create,remove}_file are the simplest, and exist in
drivers/base/fs/driver.c. If people are feeling frisky, and want to
play, use that as an example on how to extend driverfs for other
subsystems and object types.
I'm also attaching an example 'subsystem' driver that exports
registration and unregistration functions that do creation and teardown
of driverfs directories.
- Remove references to struct device in driverfs, making it completely
independent of the device model core.
- Update documentation
-pat

Note that this tree includes all the changes that I posted earlier today.
bk://ldm.bkbits.net/linux-2.5-driverfs still exists, with only the earlier
changes.
