Different classes of controllers from LSI Logic accept and respond to the

interactions. So any 'proc', 'sysfs' implementations will be localized in this
common module.

"Shared code in a third module, a "library module", is an acceptable
solution. modprobe automatically loads dependent modules, so users
running "modprobe driver1" or "modprobe driver2" would automatically
load the shared library module."

"As Jeff hinted, if your userspace<->driver API is consistent between
your new MPT-based RAID controllers and your existing megaraid driver,
then perhaps you need a single small helper module (lsiioctl or some
better name), loaded by both mptraid and megaraid automatically, which
handles registering the /dev/megaraid node dynamically. In this case,
both mptraid and megaraid would register with lsiioctl for each
adapter discovered, and lsiioctl would essentially be a switch,
redirecting userspace tool ioctls to the appropriate driver."
