[Mesa-dev] [PATCH] anv/allocator: Don't srink either end of the block pool

[Jason Ekstrand]

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.
