The prerequisite for providing the configfs interface for USB gadgets and
all their users is converting them to the new function interface from Sebastian.
This patch series serves the purpose stated above for mass storage,
usb Ethernet, FunctionFS and serial.
* The plan for the mass storage 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 plan for usb ethernet conversion is as follows:
- identify all ethernet functions (ncm, eem, ecm, ecm subset, rndis)
- identify all ethernet functions' users
| ncm | cdc2 | ether | g_ffs | multi | nokia
=========================================================
f_ncm | v | | | | |
f_eem | | | v | | |
f_ecm | | v | v | v | v | v
f_subset | | | v | v | v |
f_rndis | | | v | v | v |
- for each identified function:
a) convert to the new function inteface
b) provide compatibility for function's users
c) convert users one-by-one
d) remove compatibility
* The plan for FunctionFS conversion is as follows:
- identify all FunctionFS users (f_fs, ccg)
- make ccg not sensitive to changes in mainline (if ccg is dropped then
patch #38 can be omitted)
- convert f_fs.c to the new function interface and provide compatibility
layer
- convert g_ffs.c to use the new interface
- remove compatibility
* The plan for usb serial conversion is as follows:
- identify all serial users (g_serial, nokia - in fact not a user)
- convert f_serial to the new function interface and provide compatibility
layer
- convert g_serial to use the new interface
- remove compatibility
The series depends on Sebastian's patches found here:

It also depends on the patch:
