From c37947459172a02691ccd48cb967e8b605d38c56 Mon Sep 17 00:00:00 2001 From: Yevgeny Petrilin Date: Wed, 30 Mar 2011 23:30:17 +0000 Subject: [PATCH] mlx4: Fixing bad size of event queue buffer We should reduce the number of reserved completion queues from the total number of entries. Since the queue size is power of two, not reducing the reserved entries, caused a double queue size, which may lead to allocation failures in some cases.
