From 188f83dfe0eeecd1427d0d255cc97dbf7ef6b4b7 Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 31 Aug 2006 12:50:04 +0200 Subject: [PATCH] BLOCK: Move the msdos device ioctl compat stuff to the msdos driver [try #6] Move the msdos device ioctl compat stuff from fs/compat_ioctl.c to the msdos driver so that the msdos header file doesn't need to be included.
