kobject_set_name() uses GFP_KERNEL

[Marcel Holtmann]

Hi Kay,

all the users of kobject_set_name() which includes dev_set_name() are
allocating their memory for the device name with GFP_KERNEL. It is not a
big deal since device_add() does the same. However it is not obvious and
I ran into an issue in the Bluetooth stack where I was setting the
device name from a context that can't sleep. If this behavior is on
purpose, we better add an extra comment in the documentation.

Regards

Marcel
