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.

[PATCH] revert ide-scsi highmem cleanup
Jeff Garzik <jgarzik@pobox.com> points out that this was wrong: we need to
disable local interrupts while holding KM_IRQ0 due to IRQ sharing.
And holding interrupts off during a big PIO opration is expensive, so we only
want to do that if we know the page was highmem.

[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).

[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.

[PATCH] fix missing includes
I recently picked up my older work to remove unnecessary #includes of

from module.h. This reduces the number of indirect includes of sched.h

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.
