From e5f4b3c498623fc3d83f6d92e00a2b2dbf500cd0 Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk Date: Thu, 14 Apr 2011 17:27:29 -0400 Subject: [PATCH] xen/blkback: Fix interface.c checkpatch warnings .. except + sring_x86_64 = (struct blkif_x86_64_sring *)blkif->blk_ring_area->addr; WARNING: line over 80 characters + BACK_RING_INIT(&blkif->blk_rings.x86_64, sring_x86_64, PAGE_SIZE); as breaking them up really does not help that much.
