The name describes how amdgpu want to use the flag and not what effect
it has.
How about "allow_reserved_eviction"?
And also please update the documentation with something like:
* @allow_reserved_eviction: Allow eviction of reserved BOs.
* @resv: Reservation object to allow reserved evictions with.
Alternative we could put the ww_mutex context in here as Daniel
suggested, but I think we should stick with what we have for now and
make that change when we find another use case for this.
Christian.
