This assertion starts triggering on commit:

    anv: fix assert in wsi image code.

Before that commit, the following assertion would trigger:
texture3d: vulkan/anv_wsi.c:242: anv_wsi_image_create: Assertion `image->size == 0' failed.

    anv/allocator: Don't shrink either end of the block pool
    Previously, we only tried to ensure that we didn't shrink either end
    below what was already handed out.  However, due to the way we handle
    relocations with block pools, we can't shrink the back end at all.  It's
    probably best to not shrink in either direction.
