Hi all,
I noticed that the drm tree has been back merge into the drm-intel tree. Unfortunately, it seems that the file drivers/gpu/drm/i915/i915_gem_batch_pool.c has been resurrected.
It was removed in commit
b40d73784ffc ("drm/i915: Replace struct_mutex for batch pool serialisation")
but has come back due to a conflict with commit
52791eeec1d9 ("dma-buf: rename reservation_object to dma_resv")
from the drm tree.
