[PATCH v1 0/3] drm_buddy regresion fix and minor improvements

[Pierre-Eric Pelloux-Prayer]

Hi,

The first patch fixes a performance issue caused by a change in
drm_buddy ("drm/buddy: Implement tracking clear page feature").
It may be related to https://gitlab.freedesktop.org/drm/amd/-/issues/4260.

The other 2 patches are improvements based on my limited understanding
of the code and that seem to work as expected.


Pierre-Eric Pelloux-Prayer (3):
  drm/buddy: add a flag to disable trimming of non cleared blocks
  drm/buddy: use DRM_BUDDY_CLEAR_ALLOCATION as a hint, not a hard req
  drm/buddy: dont go over the higher orders multiple times
