Hi Tobin,

Thank you very much for your review, I will address all of your comments in
the next revision.

BTW, I found  a lock ordering issue in my work that  that I will need to
fix:

In device_shutdown() device_lock() must be taken before
devices_kset->list_lock. Instead I will use device_trylock(), and if that
fails, will drop devices_kset->list_lock and acquiring the device lock
outside, and check that the device is still in the list after taking the
list lock again.

Pavel
