The prerequisite for providing the configfs interface for mass storage and all
its users is converting them to the new function interface from Sebastian.
This patch series serves the purpose stated above.
The plan for the conversion is as follows:
- identify all users of mass storage (acm_ms, mass_storage, multi)
- get rid of #including the storage_common.c file by using separate compilation
- make f_mass_storage a separately compiled module with the new interface
a) create a header file
b) convert to the new function interface
c) provide compatibility for the mass storage's users
- convert the users of mass storage one by one to the new interface
- remove the compatibility for old style mass storage users
- merge separately compiled object files storage_common.o and f_mass_storage.o
into one module (at this point there is no purpose in having a separate utiltiy
module)
The series depends on Sebastian's series found here:

@Sebastian: Felipe reports that there are problems with applying some of
the patches in your series. Are you willing to fix the problem?
