[merged] fs-move-shared-sysctls-to-fs-sysctlsc.patch removed from -mm tree

[akpm]

The patch titled
     Subject: fs: move shared sysctls to fs/sysctls.c
has been removed from the -mm tree.  Its filename was
     fs-move-shared-sysctls-to-fs-sysctlsc.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Luis Chamberlain <mcgrof@kernel.org>
Subject: fs: move shared sysctls to fs/sysctls.c

To help with this maintenance let's start by moving sysctls to places
where they actually belong.  The proc sysctl maintainers do not want to
know what sysctl knobs you wish to add for your own piece of code, we just
care about the core logic.

So move sysctls which are shared between filesystems into a common file
outside of kernel/sysctl.c.
