The patch titled
BLOCK: Move the msdos device ioctl compat stuff to the msdos driver
has been removed from the -mm tree. Its filename is
block-move-the-msdos-device-ioctl-compat-stuff-to-the-msdos-driver.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: BLOCK: Move the msdos device ioctl compat stuff to the msdos driver
From: David Howells <dhowells@xxxxxxxxxx>
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.
