NFS4: on a O_EXCL OPEN make sure SETATTR sets the fields holding the verifier
The Linux NFS4 client simply skips over the bitmask in an O_EXCL open call and so it doesn't bother to reset any fields that may be holding the verifier. This patch has us save the first two words of the bitmask (which is all the current client has #defines for). The client then later checks this bitmask and turns on the appropriate flags in the sattr->ia_verify field for the following SETATTR call.
This patch only currently checks to see if the server used the atime and mtime slots for the verifier (which is what the Linux server uses for this). I'm not sure of what other fields the server could reasonably use, but adding checks for others should be trivial.

NFS: Add the mount option "nosharecache"
Prior to David Howell's mount changes in 2.6.18, users who mounted different directories which happened to be from the same filesystem on the server would get different super blocks, and hence could choose different mount options. As long as there were no hard linked files that crossed from one subtree to another, this was quite safe. Post the changes, if the two directories are on the same filesystem (have the same 'fsid'), they will share the same super block, and hence the same mount options.
Add a flag to allow users to elect not to share the NFS super block with another mount point, even if the fsids are the same. This will allow users to set different mount options for the two different super blocks, as was previously possible. It is still up to the user to ensure that there are no cache coherency issues when doing this, however the default behaviour will be to share super blocks whenever two paths result in the same fsid.

SUNRPC: fix hang due to eventd deadlock...
Brian Behlendorf writes:
The root cause of the NFS hang we were observing appears to be a rare deadlock between the kernel provided usermodehelper API and the linux NFS client. The deadlock can arise because both of these services use the generic linux work queues. The usermodehelper API run the specified user application in the context of the work queue. And NFS submits both cleanup and reconnect work to the generic work queue for handling. Normally this is fine but a deadlock can result in the following situation.
- NFS client is in a disconnected state
- [events/0] runs a usermodehelper app with an NFS dependent operation, this triggers an NFS reconnect.
- NFS reconnect happens to be submitted to [events/0] work queue.
- Deadlock, the [events/0] work queue will never process the reconnect because it is blocked on the previous NFS dependent operation which will not complete.`
The solution is simply to run reconnect requests on rpciod.

SUNRPC: Always match an upcall message in gss_pipe_downcall()
It used to be possible for an rpc.gssd daemon to stuff the RPC credential cache for any rpc client simply by creating RPCSEC_GSS contexts and then doing downcalls. In practice, no daemons ever made use of this feature.
Remove this feature now, since it will be impossible to figure out which mechanism a given context actually matches if we enable more than one gss mechanism to use the same upcall pipe.
