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

[Dylan Baker]

You have a typo in the commit message "srink" -> "shrink"

Quoting Jason Ekstrand (2018-04-20 22:15:00)
> 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.
