Sharing the open sequence queue causes a deadlock when we try to take
both a lock sequence id and and open sequence id.
This fixes the regression reported by Dimitri Puzin and Jeff Garzik: See
http://bugzilla.kernel.org/show_bug.cgi?id=9712
for details.

NFSv4 file locking is currently completely broken since it doesn't respect
the OPEN sequencing when it is given an unconfirmed lock_owner and needs to
do an open_to_lock_owner. Worse: it breaks the sunrpc rules by doing a
GFP_KERNEL allocation inside an rpciod callback.
Fix is to preallocate the open seqid structure in nfs4_alloc_lockdata if we
see that the lock_owner is unconfirmed.
Then, in nfs4_lock_prepare() we wait for either the open_seqid, if
the lock_owner is still unconfirmed, or else fall back to waiting on the
standard lock_seqid.

sends an OPEN_CONFIRM request with the appropriate sequence id and stateid

Sigh... commit 4584f520e1f773082ef44ff4f8969a5d992b16ec (NFS: Fix NFS
mountpoint crossing...) had a slight flaw: server can be NULL if sget()
returned an existing superblock.
Fix the fix by dereferencing s->s_fs_info.
Thanks to Coverity/Adrian Bunk and Frank Filz for spotting the bug.
(See http://bugzilla.kernel.org/show_bug.cgi?id=9647)
Also add in the same namespace Oops fix for NFSv4 in both the mountpoint
crossing case, and the referral case.

Hi Trond,
I have discovered that the BUG_ON in nfs_follow_mountpoint:
BUG_ON(IS_ROOT(dentry));
can be triggered by a misbehaving server.
What happens is the client does a lookup and discoveres that the named
directory has a different fsid, so it initiates a mount.
It then performs a GETATTR on the mounted directory and gets a
different fsid again (due to a bug in the NFS server).
This causes nfs_follow_mountpoint to be called on the newly mounted
root, which triggers the BUG_ON.
To duplicate this, have a directory which contains some mountpoints,
and export that directory with the "crossmnt" flag using nfs-utils
1.1.1 (or 1.1.0 I think)
The GETATTR on the root of the mounted filesystem will return the
information for the top exportpoint, while a lookup will return the
correct information. This difference causes the NFS client to BUG.
I think the best way to fix this is to trap this possibility early, so
just before completing the mount in the NFS client, check that it isn't
going to use nfs_mountpoint_inode_operations.
As long as i_op will never change once set (is that true?), this
should be adequately safe.
The following patch shows a possible approach, and it works for me.
i.e. when the NFS server is misbehaving, I get ESTALE on those
mountpoints, while when the NFS server is working correctly, I get
correct behaviour on the client.

Since 2.6.18, the superblock sb->s_root has been a dummy dentry with a
dummy inode. This breaks ustat(), which actually uses sb->s_root in a
vfstat() call.
Fix this by making the s_root a dummy alias to the directory inode that was
used when creating the superblock.

Commit eda3cef8dd2b83875affe82595db9d0c278879b2 ("NFS: Fix error
handling in nfs_direct_write_result()") ensured that if a WRITE returns
an error, then data->res.verf->committed is not tested (as it is not
initialised).
Then commit 60fa3f769f7651a60125a0f44e3ffe3246d7cf39 ("NFS: Fix two bugs
in the O_DIRECT write code") inadvertently reverted this while fixing
other problems.
So move the test so that we never examine ->committed in an error case,
and fix a speeling error while we are there.

lookup() and sillyrename() can race one another because the sillyrename()
completion cannot take the parent directory's inode->i_mutex since the
latter may be held by whoever is calling dput().
We therefore have little option but to add extra locking to ensure that
nfs_lookup() and nfs_atomic_open() do not race with the sillyrename
completion.
If somebody has looked up the sillyrenamed file in the meantime, we just
transfer the sillydelete information to the new dentry.

This patch fixes a regression that was introduced by commit
44dd151d5c21234cc534c47d7382f5c28c3143cd
We cannot zero the user page in nfs_mark_uptodate() any more, since
a) We'd be modifying the page without holding the page lock
b) We can race with other updates of the page, most notably
because of the call to nfs_wb_page() in nfs_writepage_setup().
Instead, we do the zeroing in nfs_update_request() if we see that we're
creating a request that might potentially be marked as up to date.

These patches aim to improve balance_dirty_pages() and directly address three
issues:
1) inter device starvation
2) stacked device deadlocks
3) inter process starvation
1 and 2 are a direct result from removing the global dirty limit and using
per device dirty limits. By giving each device its own dirty limit is will
no longer starve another device, and the cyclic dependancy on the dirty limit
is broken.
In order to efficiently distribute the dirty limit across the independant
devices a floating proportion is used, this will allocate a share of the total
limit proportional to the device's recent activity.
3 is done by also scaling the dirty limit proportional to the current task's
recent dirty rate.
