slab does this already, and I want to use this in a memory allocation
tracker in drm for stuff that's tied to the lifetime of a drm_device,
not the underlying struct device. Kinda like devres, but for drm.

Ack for merging through drm trees very much appreciated.

Would be better to export it without underscores.

But ok.
