Hi Linus,

After merging the spi-current tree, today's linux-next build (x86_64
allmodconfig) failed like this:

include/linux/sysctl.h:28: included file 'linux/rcupdate.h' is not exported

Caused by commit dfef6dcd35cb ("unf*ck proc_sysctl ->d_compare()").

I applied this patch for today:

From: Stephen Rothwell <redacted>
Date: Thu, 10 Mar 2011 11:14:17 +1100
Subject: [PATCH] sysctl: the include of rcupdate.h is only needed in the kernel

Fixes this built error:

include/linux/sysctl.h:28: included file 'linux/rcupdate.h' is not exported
