[PATCH v2 0/3] usb: gadget: f_fs: userspace API fixes and improvements

[Robert Baldyga]

This patchset contains changes in FunctionFS making it easier and
safer to use. It introduces virtual address mapping which allows
to separate endpoint address space in function from physical endpoint
addresses, and allow to refer to endpoints with address chosen by user.
It also adds new ioctl allowing to obtain endpoint descriptor, and
introduces new endpoint files naming convention to unify number identifying
each single endpoint.

Changelog:
