      [PATCH] ppc64: Change to new OF device tree API, from Nathan Lynch · 40399e6d
      Andrew Morton authored
      From: Anton Blanchard <anton@samba.org>
      
      Attached is a patch which replaces all the uses of the old device tree API in
      arch/ppc64.  Patch is against 2.6.0-test5 (cset 1.1328) from ameslab bk, plus
      the patch from my previous message.  I've tested this on a pSeries LPAR.

      [PATCH] ppc64: New Open Firmware device tree API, from Nathan Lynch · 4e0cbcfe
      Andrew Morton authored
      From: Anton Blanchard <anton@samba.org>
      
      This is an adaptation of the new Open Firmware device tree traversal API from
      ppc32, originally written by Benjamin Herrenschmidt.  This patch is against
      2.6.0-test3, but should apply ok to the latest 2.5 ameslab tree.
      
      These functions are meant to be SMP-safe alternatives to the current set of
      query/traversal routines (find_devices, find_type_devices, et al).

      [PATCH] raw.c refcounting fix · a15092bd
      Andrew Morton authored
      From: viro@parcelfarce.linux.theplanet.co.uk
      
      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] cramfs: use pagecache better · 5524f26f
      Andrew Morton authored
      From: viro@parcelfarce.linux.theplanet.co.uk
      
      	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.

      [PATCH] bdev: add I_BDEV() · 8fbd544c
      Andrew Morton authored
      From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk>
      
      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.

      Andrew Morton authored
      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.

      [PATCH] bdev: presto conversion · 2b11e518
      Andrew Morton authored
      From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk>
      
      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...

      [PATCH] bdev: open() changes · a1864a75
      Andrew Morton authored
      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, ...)

      [PATCH] loop: fix hard sector size · 9644d0d9
      Andrew Morton authored
      From: Ben Slusky <sluskyb@paranoiacs.org>
      
      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
