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 <lockwood@xxxxxxxxxxx> Benoit Goby <benoit@xxxxxxxxxxx> Colin Cross <ccross@xxxxxxxxxxx> Arve Hjønnevåg <arve@xxxxxxxxxxx> Peter Oh <poh@xxxxxxxxxxxx> Greg Hackmann <ghackmann@xxxxxxxxxx> Badhri Jagan Sridharan <Badhri@xxxxxxxxxx> 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.
