From 0d9dd5c3221409df58dc612bacb7f12be26b319b Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Mon, 23 Mar 2020 15:49:00 +0100 Subject: [PATCH] UPSTREAM: mm/sl[uo]b: export __kmalloc_track(_node)_caller 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.
