I understand that, the question was more on what is the significance
of that for this specific API ?
There are a lot of slow path APIs in evendev and all other library
none of them use it.
It just put into different section of binary and optimize more for
size. I think, there is no specific reason to add this ONLY for this
API
to make it standout.

Also, The cold attribute is not implemented in GCC versions earlier than 4.3.
