So do you want to take the position:
Hey driver authors: you cannot use any shared lock on module removal and on sysfs ops?
Yes, I would not recommend using such a lock at all. sysfs operations happen on a per-device basis, so you can lock the device structure.
All devices are going to be removed on module removal and so cannot be locked.
