This is the second half of the changes to make the irq_desc_ptrs be

filesystem freeze: add error handling of write_super_lockfs/unlockfs
Currently, ext3 in mainline Linux doesn't have the freeze feature which
suspends write requests. So, we cannot take a backup which keeps the
filesystem's consistency with the storage device's features (snapshot and
replication) while it is mounted.
In many case, a commercial filesystem (e.g. VxFS) has the freeze feature
and it would be used to get the consistent backup.
If Linux's standard filesystem ext3 has the freeze feature, we can do it
without a commercial filesystem.
So I have implemented the ioctls of the freeze feature.
I think we can take the consistent backup with the following steps.
1. Freeze the filesystem with the freeze ioctl.
2. Separate the replication volume or create the snapshot
with the storage device's feature.
3. Unfreeze the filesystem with the unfreeze ioctl.
4. Take the backup from the separated replication volume
or the snapshot.
This patch:
VFS:
Changed the type of write_super_lockfs and unlockfs from "void"
to "int" so that they can return an error.
Rename write_super_lockfs and unlockfs of the super block operation
freeze_fs and unfreeze_fs to avoid a confusion.
ext3, ext4, xfs, gfs2, jfs:
Changed the type of write_super_lockfs and unlockfs from "void"
to "int" so that write_super_lockfs returns an error if needed,
and unlockfs always returns 0.
reiserfs:
Changed the type of write_super_lockfs and unlockfs from "void"
to "int" so that they always return 0 (success) to keep a current behavior.

x86: only scan the root bus in early PCI quirks
We found a situation on Linus' machine that the Nvidia timer quirk hit on
a Intel chipset system. The problem is that the system has a fancy Nvidia
card with an own PCI bridge, and the early-quirks code looking for any
NVidia bridge triggered on it incorrectly. This didn't lead a boot
failure by luck, but the timer routing code selecting the wrong timer
first and some ugly messages. It might lead to real problems on other
systems.
I checked all the devices which are currently checked for by early_quirks
and it turns out they are all located in the root bus zero.
So change the early-quirks loop to only scan bus 0. This incidently also
saves quite some unnecessary scanning work, because early_quirks doesn't
go through all the non root busses.
The graphics card is not on bus 0, so it is not matched anymore.

block: fix bug in ptbl lookup cache
Neil writes:
Hi Jens,
I've found a little bug for you. It was introduced by
a6f23657d3072bde6844055bbc2290e497f33fbc
block: add one-hit cache for disk partition lookup
and has the effect of killing my machine whenever I try to assemble
an md array :-(
One of the devices in the array has partitions, and mdadm always
deletes partitions before putting a whole-device in an array (as it
can cause confusion). The next IO to that device locks the machine.
I don't really understand exactly why it locks up, but it happens in
disk_map_sector_rcu(). This patch fixes it.
Which is due to a missing clear of the (now) stale partition lookup
data. So clear that when we delete a partition.

Btrfs: explicitly mark the tree log root for writeback
Each subvolume has an extent_state_tree used to mark metadata
that needs to be sent to disk while syncing the tree. This is
used in addition to the dirty bits on the pages themselves so that
a single subvolume can be sent to disk efficiently in disk order.
Normally this marking happens in btrfs_alloc_free_block, which also does
special recording of dirty tree blocks for the tree log roots.
Yan Zheng noticed that when the root of the log tree is allocated, it is added
to the wrong writeback list. The fix used here is to explicitly set
it dirty as part of tree log creation.
