Subject: linux-next: block tree build failure

Hi Jens,

Today's linux-next build (powerpc allyesconfig) failed like this:

block/blk-cgroup.c: In function 'blkiocg_create':
block/blk-cgroup.c:285: error: implicit declaration of function 'ERR_PTR'
block/blk-cgroup.c:285: warning: return makes pointer from integer without a cast
block/blk-cgroup.c:289: warning: return makes pointer from integer without a cast

Caused by commit 31e4c28d95e64f2d5d3c497a3ecf37c62de635b4 ("blkio:
Introduce blkio controller cgroup interface").

I applied this patch for today:

From: Stephen Rothwell <sfr@...b.auug.org.au>
Date: Mon, 7 Dec 2009 19:29:39 +1100
Subject: [PATCH] block: include linux/err.h to use ERR_PTR
