Does equivalent of up_write(&s->s_umount); deactivate_super(s);
However, it does not does not unlock it until it's all over.
As the result, it's safe to use to dispose of new superblock on ->get_sb()
failure exits - nobody will see the sucker until it's all over.
Equivalent using up_write/deactivate_super is safe for that purpose
if superblock is either safe to use or has NULL ->s_root when we unlock.
Normally filesystems take the required precautions, but
a) we do have bugs in that area in some of them.
b) up_write/deactivate_super sequence is extremely common,
so the helper makes sense anyway.

With Al Viro's patch to move privroot lookup to fs mount, there's no need
to have special code to hide the privroot in reiserfs_lookup.
I've also cleaned up the privroot hiding in reiserfs_readdir_dentry and
removed the last user of reiserfs_xattrs().

The xattr_root caching was broken from my previous patch set. It wouldn't
cause corruption, but could cause decreased performance due to allocating
a larger chunk of the journal (~ 27 blocks) than it would actually use.
This patch loads the xattr root dentry at xattr initialization and creates
it on-demand. Since we're using the cached dentry, there's no point
in keeping lookup_or_create_dir around, so that's removed.

2.6.30-rc3 introduced some sanity checks in the VFS code to avoid NFS
bugs by ensuring that lookup_one_len is always called under i_mutex.
This patch expands the i_mutex locking to enclose lookup_one_len. This was
always required, but not not enforced in the reiserfs code since it
does locking around the xattr interactions with the xattr_sem.
This is obvious enough, and it survived an overnight 50 thread ACL test.

This fixes the following circular locking dependency problem:
=======================================================
[ INFO: possible circular locking dependency detected ]
2.6.30-rc3 #5
-------------------------------------------------------
segctord/3895 is trying to acquire lock:
(&nilfs->ns_writer_mutex){+.+...}, at: [<d0d02172>]
nilfs_mdt_get_block+0x89/0x20f [nilfs2]
but task is already holding lock:
(&bmap->b_sem){++++..}, at: [<d0d02d99>]
nilfs_bmap_propagate+0x14/0x2e [nilfs2]
which lock already depends on the new lock.
The bugfix is done by replacing call sites of nilfs_get_writer() which
are never called from read-only context with direct dereferencing of
pointer to a writable FS-instance.

Some function calls in nilfs_prepare_segment_for_recovery() may fail
because they can create blocks on meta data files without configuring
a writable FS-instance. Concretely, nilfs_mdt_create_block() routine
of meta data files will fail in that case.
This fixes the problem by temporarily attaching a writable FS-instace
during the function is called.

This patch (as1238) adds proper reference counting for ftdi_sio's
private data structure. Without it, the driver will free the
structure while it is still in use if the user unplugs the serial
device before closing the device file.
The patch also replaces a slightly dangerous
cancel_delayed_work/flush_scheduled_work pair with
cancel_delayed_work_sync, which is always safer.

This reverts commit 006f4571a15fae3a0575f2a0f9e9b63b3d1012f8:
This patch moves platform_data from struct device into
struct platform_device, based on the two ideas:
1. Now all platform_driver is registered by platform_driver_register,
which makes probe()/release()/... of platform_driver passed parameter
of platform_device *, so platform driver can get platform_data from
platform_device;
2. Other kind of devices do not need to use platform_data, we can
decrease size of device if moving it to platform_device.
Taking into consideration of thousands of files to be fixed and they
can't be finished in one night(maybe it will take a long time), so we
keep platform_data in device to allow two kind of cases coexist until
all platform devices pass its platfrom data from
platform_device->platform_data.
All patches to do this kind of conversion are welcome.
As we don't really want to do it, it was a bad idea.

This reverts commit ce21c7bcd796fc4f45d48781b7e85f493cc55ee5:
We will remove platform_data field from struct device until
all platform devices pass its specific data from platfom_device
and all platform drivers use platform specific data passed by
platform_device->platform_data. This kind of conversion will
need a long time, for thousands of files is affected.
To make the conversion easily, we allow platform specific data
passed by struct device or struct platform_device and platform
driver may use it from struct device or struct platform_device.
As we really don't want to do this at all.

We re-named 'DYNAMIC_PRINTK_DEBUG' to 'DYNAMIC_DEBUG' in 2.6.30....
'PRINTK_DEBUG' as pointed out never existed. So, it appears to be
extraneous, and should be removed. thanks for pointing it out.

This fixes the use of fwmarks to denote IPv4 virtual services
which was unfortunately broken as a result of the integration
of IPv6 support into IPVS, which was included in 2.6.28.
The problem arises because fwmarks are stored in the 4th octet
of a union nf_inet_addr .all, however in the case of IPv4 only
the first octet, corresponding to .ip, is assigned and compared.
In other words, using .all = { 0, 0, 0, htonl(svc->fwmark) always
results in a value of 0 (32bits) being stored for IPv4. This means
that one fwmark can be used, as it ends up being mapped to 0, but things
break down when multiple fwmarks are used, as they all end up being mapped
to 0.
As fwmarks are 32bits a reasonable fix seems to be to just store the fwmark
in .ip, and comparing and storing .ip when fwmarks are used.
This patch makes the assumption that in calls to ip_vs_ct_in_get()
and ip_vs_sched_persist() if the proto parameter is IPPROTO_IP then
we are dealing with an fwmark. I believe this is valid as ip_vs_in()
does fairly strict filtering on the protocol and IPPROTO_IP should
not be used in these calls unless explicitly passed when making
these calls for fwmarks in ip_vs_sched_persist().
