RFC on Android's ConfigFS based MTP function implementation and usage
of Uevents to notify the userspace about the USB state changes.
The MTP function is based on years of work originally done in the
Android kernel tree by:
Mike Lockwood <[email protected]>
Benoit Goby <[email protected]>
Colin Cross <[email protected]>
Arve Hjønnevåg <[email protected]>
Peter Oh <[email protected]>
Greg Hackmann <[email protected]>
Badhri Jagan Sridharan <[email protected]>
The Uevent notification patch is more of an RFC than an actual
submission. It is based on Android patchset originaly authored by
Badhri to send uevent notifications to Android userpace for USB
state changes.
I've folded the series up to make it easier to review, provided a
coherent patch description and modified it enough that I don't want
them to be blamed for any mistakes I've made condensing their patches
down.
Thoughts and feedback would be appreciated.
Thanks,
Amit Pundir
