[PATCH 01/52] mm/sl[uo]b: export __kmalloc_track(_node)_caller

[PATCH 01/52] mm/sl[uo]b: export __kmalloc_track(_node)_caller

[Daniel Vetter]

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.

Thanks, Daniel

Would be better to export it without underscores.

But ok.
