e6d7202b66 fs/char_dev.c: remove unused cdev_index()
Commit 66fa12c571 ("ieee1394: remove the old IEEE 1394 driver stack")
eliminated the only user of cdev_index().  So it can be removed too.

9fd5746fd3 fs: Remove i_cindex from struct inode
The only user of the i_cindex element in the inode structure is used
is by the firewire drivers.  As part of an attempt to slim down the
inode structure to save memory --- since a typical Linux system will
have hundreds of thousands if not millions of inodes cached, a
reduction in the size inode has high leverage.

The firewire driver does not need i_cindex in any fast path, so it's
simple enough to calculate when it is needed, instead of wasting space
in the inode structure.

Remove the "#ifdef __KERNEL__" tests from unexported header files in
linux/include whose entire contents are wrapped in that preprocessor
test.

3d8b3036f5 [PATCH] cdev.h: forward declarations
Apparently this broke due to missing `struct inode' declaration.

5ec68b2e31 [PATCH] pull in necessary header files for cdev.h
linux/cdev.h uses struct kobject and other structs and should therefore
include them.  Currently, a module either needs to add the missing includes
itself, or, in case a module includes other headers already, needs to put
<linux/cdev.h> last, which goes against a alphabetically-sorted include
list.

5da6185bca [PATCH] NOMMU: Set BDI capabilities for /dev/mem and /dev/kmem
Set the backing device info capabilities for /dev/mem and /dev/kmem to
permit direct sharing under no-MMU conditions and full mapping capabilities
under MMU conditions.  Make the BDI used by these available to all directly
mappable character devices.

Also comment the capabilities for /dev/zero.

99ac48f54a [PATCH] mark f_ops const in the inode
Mark the f_ops members of inodes as const, as well as fix the
ripple-through this causes by places that copy this f_ops and then "do
stuff" with it.

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
