[PATCH v2 bpf-next 0/2] drm, bpf: User drm_mm in bpf

[Alexei Starovoitov]

From: Alexei Starovoitov <ast at kernel.org>

Hi DRM folks,

we'd like to start using drm_mm in bpf arena.
The drm_mm logic fits particularly well to bpf use case.
See individual patches.
objdump -h lib/drm_mm.o 
.text         000012c7
So no vmlinux size concerns.

v1->v2:
- Fix build issues and add Acks.

Alexei Starovoitov (2):
  drm, bpf: Move drm_mm.c to lib to be used by bpf arena
  bpf: Switch bpf arena to use drm_mm instead of maple_tree
