The way I see it is that user writes number of luns it wants the gadget to have into a configfs file at which point the function creates lun# directories so that each lun can be configured separately. >>I also show how to write an adapter module, which provides >>the old sysfs-based interface to mass storage with module parameters, >>but internally operates on configfs. > There is no sysfs interface, is there?

This, among other things, allows setting up of the backing file if the LUN is removable. -- Best regards, _ _ .o. | Liege of Serenely Enlightened Majesty of o' \,=./ `o ..o | Computer Science, Michał “mina86” Nazarewicz (o o) ooo +----<email/xmpp: m...@google.com>--------------ooO--(_)--Ooo--
