From 3db93f9128e5329f6658c9018cf23eb31807c24c Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Fri, 20 Apr 2018 21:52:41 -0700 Subject: [PATCH] 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.
