ARCHIVE: nv_drm_gem_handle_create_drop_reference is broken

[YusufKhan-gamedev]

nv_drm_gem_handle_create_drop_reference calls drm_gem_handle_create without passing a pointer to the handle that is not good.

This is not good

open: Success

The last line is the pointer to the handle I assume it should be the real gem handle(Im awful at visualizing pointers)

Question: Can I use that handle in gem ioctls in any way? I tried passing the handle and the pointer to the handle to nvidia_get_gem_map_offset and both returned 160.

Also if the answer is yes then please for the sake of ABI stability could there be a v2 of the gem ioctls instead of outright removing it? I believe we could remove it 3-4 months after 510 is EOL?

Its already a pointer lmao, the real issue is that the handle pointers are negative in userland and thats because its not!
