David Chinner e8c8b3a79d [XFS] Introduce two new mount options (nolargeio/largeio) to allow
filesystems to expose the filesystem stripe width in stat(2) rather than
the page cache size. This allows applications requiring high bandwidth to
easily determine the optimum I/O size for the underlying filesystem. The
default is to report the page cache size (i.e. "nolargeio").

Christoph Hellwig f538d4da8d [XFS] write barrier support Issue all log sync operations as ordered
writes.  In addition flush the disk cache on fsync if the sync cached
operation didn't sync the log to disk (this requires some additional
bookeping in the transaction and log code). If the device doesn't claim to
support barriers, the filesystem has an extern log volume or the trial
superblock write with barriers enabled failed we disable barriers and
print a warning.  We should probably fail the mount completely, but that
could lead to nasty boot failures for the root filesystem.  Not enabled by
default yet, needs more destructive testing first.

James Courtier-Dutton d83c671fb7 [PATCH] Creative Audigy 2 cardbus: Add IO window wakeup magic
This adds the magic IO wakeup code for the CardBus version of the
Creative Labs Audigy 2 to the snd-emu10k1 driver.

Without the magic IO enable sequence, reading from the IO region of the
card will fail spectacularly, and the machine will hang.

My next task will be getting the driver to actually play sound without
distortion.

[ This is a work-in-progress, but since it avoids a total lockup

  card inserted, we're better off with it than without it, even
  if sound quality is bad right now ]

Andrea Arcangeli 659603ef69 [PATCH] fix __writeback_single_inode WARN_ON
When the inode count is zero in inode writeback, the

	WARN_ON(!(inode->i_state & I_WILL_FREE));

is broken, and needs to test for either I_WILL_FREE|I_FREEING.

When the inode is in I_FREEING state, it's already out of the visibility
of the vm so it can't be freed so it doesn't require the __iget and the
generic_delete_inode path can call the sync internally to the lowlevel
fs callback during the last iput. So the inode being in I_FREEING is
also a valid condition for calling the sync with i_count == 0.

The specific stack trace is this:

Jens Axboe 581c1b1439 [PATCH] noop-iosched: avoid corrupted request merging
Tejun Heo notes:

   "I'm currently debugging this.  The problem is that we are using the
    generic dispatch queue directly in the noop sched and merging is NOT
    allowed on dispatch queues but generic handling of last_merge tries
    to merge requests.  I'm still trying to verify this, so I'll be back
    with results soon."

In the meantime, disable merging for noop by setting REQ_NOMERGE in
elevator_noop_add_request().

Eventually, we should add a noop_list and do the dispatching like in the
other io schedulers.  Merging is still beneficial for noop (and it has
always done it).

Jeff Garzik 005a5a06a6 [libata] locking rewrite (== fix)
A lot of power packed into a little patch.

This change eliminates the sharing between our controller-wide spinlock
and the SCSI core's Scsi_Host lock.  As the locking in libata was
already highly compartmentalized, always referencing our own lock, and
never scsi_host::host_lock.

As a side effect, this change eliminates a deadlock from calling
scsi_finish_command() while inside our spinlock.

Tim Schmielau 4e57b68178 [PATCH] fix missing includes
I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.

In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch.  This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other.  So if any
hunk rejects or gets in the way of other patches, just drop it.  My scripts
will pick it up again in the next round.
