-Subject: [PATCH 055/134] mm: Add min_free_order_shift tunable.
-MIME-Version: 1.0
-Content-Type: text/plain; charset=utf-8
-Content-Transfer-Encoding: 8bit
-
-By default the kernel tries to keep half as much memory free at each
-order as it does for one order below. This can be too agressive when
-running without swap.
