raw.c has a refcounting bug (patch attached).

As for the theory...  If you have a pathname - use filp_open() or
open_bdev_excl() and be done with that.  bdget() et.al.  are OK only if you
really have nothing better than device number and that's a situation that
should be avoided unless you really have no choice.

Said that, we have the following primitives:

* lookup_bdev(): takes a pathname, returns a reference to block_device.

* bdget(): takes a number, returns a reference to block_device.

* blkdev_get(): takes a reference to block_device and opens it.  If open
  fails - drops the reference to block_device passed to it.

* blkdev_put(): takes a reference to block_device and closes it.  The
  reference is dropped.

* bdput(): drops a reference to block_device.

Note that behaviour of blkdev_get() and blkdev_put() is such that it makes
for minimal cleanup code.

bd_claim()/bd_release() is the exclusion mechanism - that's what mount,
swapon, open with O_EXCL, etc.  are using to avoid stepping on each others
toes.  bd_claim() claims bdev for given owner; if it's already owned and
not by the same owner you'll get -EBUSY.  bd_release() reverts the effect
of bd_claim().  Note that if you claim the thing N times (with the same
owner, obviously), you'll need N bd_release() before it stops being owned.

raw.c grabbed a reference to bdev only after blkdev_get().  If blkdev_get()
failed (e.g.  media being absent), you've got an unbalanced bdput().

	Patch switches cramfs_read() to direct use of pagecache and
eliminates all messing with buffer_heads.  Fixes the interaction with
ramdisk (there set_blocksize() simply killed the ramdisk contents) and
gets code less brittle overall.

For bdevfs inodes (ones created along with struct block_device by
fs/block_dev.c) we have inode->i_bdev equal to &BDEV_I(inode)->bdev (i.e.
it's at the constant offset from inode).  New helper added for such inodes
(I_BDEV(inode)).  A bunch of places (mostly in block_dev.c) switched to use
of that helper.  A bunch of places that used

	file->f_dentry->d_inode->i_bdev->bd_inode

switched to

	file->f_mapping->host

- those expressions are equal whenever the former is valid.

generic_write_checks() had lost the first argument (inode) - it can be

bd_acquire() made static, switched to returning the block_device it had

generic_osync_inode() got an extra argument - mapping and doesn't calculate
inode->i_mapping anymore.  Callers updated and switched to use of
->f_mapping.

From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk>

More uses of ->i_mapping switched to uses of ->f_mapping - stuff that was not
caught by the earlier f_mapping conversion.

From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk>

In a bunch of places we used file->f_dentry->d_inode->i_sem to protect
fdatasync et.al.  Replaced with corrent file->f_mapping->host->i_sem - the
object we are protecting is address_space, so we want an exclusion that would
work for redirected ->i_mapping.  For normal files (not coda, not bdev) it's
all the same, of course - there we have

 	file->f_mapping->host == file->f_dentry->d_inode

and change above is an equivalent transfromation.

From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk>

A lot of places used to use ->f_dentry->d_inode->i_mapping all over the
place.  Replaced with use of ->f_mapping.  For now - just the places where we
literally could do search-and-replace.

New field of struct file - ->f_mapping.  We maintain the following:

presto_journal_close() switched to passing struct presto_file_data * instead
of bogus struct file *.  The only field of struct file we used to look at was
file->private_data and most of the callers allocated on-stack struct file,
assigned file.private_data and passed the sucker to presto_journal_close().
Idiocy removed.

Looks like they started with case where the data they wanted all along was,
indeed, in ->private_data of already available struct file, so they just
passed pointer to struct file.  And when they found that they need to call it
in other places where there was no such struct file, they'd done it the dumb
way instead of fixing the prototype...

Trivial cleanup in blkdev_put() - replace bdev->bd_inode->i_bdev with bdev.

The first of a series which move us toward blockdev hotplug support.  After
these we have achieved the following:

a) For "normal" (not bdevfs) inodes of block devices we never look at
   ->i_mapping.

b) For the same inodes we only look at ->i_bdev in bd_acquire() where it's
   used only as "here's what we'd found the last time" sort of cached value.
   If it's NULL, we just recalculate it.

c) Lots of messy expressions had been trimmed down, while we are at it.

(a) and (b) allow us to start doing proper block hotplug - we can destroy the
association between inode and bdev at any time, unhash bdev in question and
have new open() do everything from scratch, without waiting for old opened
files to close.  The goal is to be able to say "revoke everything over that
gendisk"/"revoke that partition" and have it do the right thing.


This patch:

Where the old code called (block device) ->open(inode, file), use
->open(inode->i_bdev->bd_inode, file).  Changes in drivers:

* none to those that only used inode->i_bdev and inode->i_rdev in their
  ->open() (bdev->bd_inode->i_bdev == bdev, so we are OK)

* floppy.c and floppy98.c used to call permission(inode, ...) in
  floppy_open().  Switched to permission(file->f_dentry->d_inode, ...)

We need to set the hardsect_size of the loop device to that of the real
device.

The loop device advertises a block size of 1024 even when configured over a
cdrom.

When burning a ext2 on a cd, and mounting it directly, I get:

	blocksize=2048;

when I losetup /dev/loop0 /dev/cdrom, and then try to mount, I get:

blocksize=1024; and then misaligned transfer; this results in not being able
to read the superblock.

The loop device should be changed to export the same blocksize of the
underlying device

This patch adds support for the Kyro graphics boards (STG4000/PowerVR
3/etc= .) to 2.6.  This is a direct port and substantial cleanup / rewrite
of the 2.4 driver that's available in the sh64 tree at linux-sh.bkbits.net.

Some of the overlay code and the STG4000 bits are still a bit ugly, so be
forewarned.

Here's a rather large update for SH (this is a bit large mainly since a
number of things have piled up, and Linus didn't want any of this during
feature freeze time). All of these changes are specific to the SH platform,
and as such, shouldn't effect any other platforms.

This dead code was introduced in kernel 2.4.19 and hasn't been updated
since.

Noticed by Christophe Saout <christophe@saout.de>.

This code has been dead since kernel 2.4.2 and it is bogus too.
