Re: [Intel-gfx] [PATCH] drm: Take ownership of the dmabuf->obj when exporting

Currently the reference for the dmabuf->obj is incremented for the dmabuf in drm_gem_prime_handle_to_fd() (at the high level userspace interface), but is released in drm_gem_dmabuf_release() (the lowlevel handler). Improve the symmetry of the dmabuf->obj ownership by acquiring the reference in drm_gem_dmabuf_export(). This makes it easier to use the prime functions directly.
