That's all right.

I hadn't noticed that g_file_storage and g_mass_storage differ in their default values for "removable". I agree, the default ought to be "n". (On the other hand, the default _is_ documented -- but you have to look at the source code to see it: lines 126-127 of drivers/usb/gadget/f_mass_storage.c.) The author of g_mass_storage ought to be able to explain the reason why the default was changed. Perhaps he'll be willing to switch it back.
