From c20f5b9633bb0953bd2422f0f1430a2028cdbd0a Mon Sep 17 00:00:00 2001 From: Andy Grover Date: Wed, 7 Jul 2010 16:46:26 -0700 Subject: [PATCH] RDS/IB: Use SLAB_HWCACHE_ALIGN flag for kmem_cache_create() We are *definitely* counting cycles as closely as DaveM, so ensure hwcache alignment for our recv ring control structs.
