From aa98aa31987ad9831711ae71ea2270228ab62532 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 14 Dec 2009 12:50:05 +1100 Subject: [PATCH] md: move compat_ioctl handling into md.c The RAID ioctls are only implemented in md.c, so the handling for them should also be moved there from fs/compat_ioctl.c.
