From 2dceba14ef0e62738d58777a1bd4018130d47a74 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 6 Nov 2009 08:09:03 +0000 Subject: compat: add struct compat_ifreq etc to compat.h In order to move socket ioctl conversion code into multiple places in the socket code, we need a common defintion of the data structures it uses. Also change the name from ifreq32 to compat_ifreq to follow the naming convention for compat.h Signed-off-by: Arnd Bergmann Signed-off-by: David S.

The definition of struct compat_ifreq was missing an ifru_settings fields that is needed to support SIOCWANDEV, so add that and clean up the whitespace damage in the struct definition.
