These checks are obviously pointless because kfree() can handle null
dereferences.

But really the main problem is that if the pointers were null that would
cause problems on the ealier lines.  The dereferences would cause an
oops and the _release() functions use ->priv to determine which IRQ to
free.  I looked into it and quite a few of the detach functions assume
link->priv is non-null.  It seems like we can remove these checks.

Some comedi drivers should return an error from their 'open' method when
something goes wrong.  Change the prototype of the 'open' method in
'struct comedi_device' to allow this, and change the drivers that use it.
Propagate any error to the 'open' file operation.

The corresponding 'close' method won't be called when the 'open' method
fails, so drivers failing the 'open' need to clean up any mess they
created.

The dt9812 and serial2002 drivers can now return an error on 'open'.
The jr3_pci driver also uses the 'open' method but doesn't fail it.

  Revert "PCI: create function symlinks in /sys/bus/pci/slots/N/"
  PCI: change resource collision messages from KERN_ERR to KERN_INFO

Yannick found that video does not work with 2.6.34.  The cause of this
bug was that the BIOS had assigned the wrong range to the PCI bridge
above the video device.  Before 2.6.34 the kernel would have shrunk
the size of the bridge window, but since
  d65245c3 PCI: don't shrink bridge resources
the kernel will avoid shrinking BIOS ranges.

So zero out the old range if we fail to claim it at boot time; this will
cause us to allocate a new range at startup, restoring the 2.6.34
behavior.

Fixes regression https://bugzilla.kernel.org/show_bug.cgi?id=16009.

Add a check to the probe function to avoid oopses like:

If btrfs_ioctl_snap_destroy() deletes a snapshot but finishes
with end_transaction(), the cleaner kthread may come in and
drop the root in the same transaction.  If that's the case, the
root's refs still == 1 in the tree when btrfs_del_root() deletes
the item, because commit_fs_roots() hasn't updated it yet (that
happens during the commit).

This wasn't a problem before only because
btrfs_ioctl_snap_destroy() would commit the transaction before dropping
the dentry reference, so the dead root wouldn't get queued up until
after the fs root item was updated in the btree.

Since it is not an error to drop the root reference and the root in the
same transaction, just drop the BUG_ON() in btrfs_del_root().

when used Posix File System Test Suite(pjd-fstest) to test btrfs,
some cases about setfacl failed when noacl mount option used.
I simplified used commands in pjd-fstest, and the following steps
can reproduce it.
------------------------
# cd btrfs-part/
# mkdir aaa
# setfacl -m m::rw aaa    <- successed, but not expected by pjd-fstest.
------------------------
I checked ext3, a warning message occured, like as:
  setfacl: aaa/: Operation not supported
Certainly, it's expected by pjd-fstest.

So, i compared acl.c of btrfs and ext3. Based on that, a patch created.
Fortunately, it works.

  user::rwx           <- successed to setfacl

but we should prohibit it that user2 changing user1's acl.

  setfacl: aaa: Operation not permitted
