NFSv4: Don't use the delegation->inode in nfs_mark_return_delegation()

nfs_mark_return_delegation() is usually called without any locking, and
so it is not safe to dereference delegation->inode. Since the inode is
only used to discover the nfs_client anyway, it makes more sense to
have the callers pass a valid pointer to the nfs_server as a parameter.

nfs: don't use d_move in nfs_async_rename_done

If the task that initiated the sillyrename ends up being killed by a
fatal signal, then it will eventually return back to userspace and end
up releasing the i_mutex. d_move however needs to be done while holding
the i_mutex.

Instead of using d_move here, just unhash the old and new dentries to
prevent them from being found by lookups. With this change though, the
dentries are now incorrect post-rename and do not reflect the actual
name of the file on the server. I'm proceeding under the assumption
that since they are unhashed that this isn't really a problem.

In order for the sillydelete to still work though, the dname must be
copied earlier when setting up the sillydelete info, and the name must
be recopied if the sillydelete info has to be moved to a new dentry.

If we're writing back data, and the FLUSH_STABLE flag is set, then we
always want to use NFS_FILE_SYNC, since we're always in a situation where
we're doing page reclaim, and so we want to free up the page as quickly
as possible.

If we're in the FLUSH_COND_STABLE case, then we either want to use another
unstable write (if we have to do a commit anyway) or again, we want to
use NFS_FILE_SYNC because we know that we have no more pages to write
out.

NFS: pnfs: loop over multipath addrs on connect

Don't just use the first addr in the multipath list - instead, loop
over addresses when calling nfs4_set_ds_client() (which calls connect)
until it is successful.

Although this is not real multipath support, it's a quick fix to handle when
an MDS sends a list of addresses for a DS and some of the addr families are
unsupported or misconfigured (like no routable ipv6 addr assigned).
This will attempt all paths to the DS before giving up, instead of immediately
falling back to the MDS.

As before, an error encountered after a successful connect() will cause all
i/o to fall back to the MDS.

NFS: Parse and store all multipath DS addresses

This parses and stores all addresses associated with each data server,
laying the groundwork for supporting multipath to data servers.

- Skips over addresses that cannot be parsed (ie IPv6 addrs if v6 is not
enabled). Only fails if none of the addresses are recognizable
- Currently only uses the first address that parsed cleanly
- Tested against pynfs server (modified to support multipath)

NFS: pnfs IPv6 support

Handle ipv6 remote addresses from GETDEVICEINFO

- supports netid "tcp" for ipv4 and "tcp6" for ipv6 as rfc 5665 specifies
- added ds_remotestr to avoid having to handle different AFs in every dprintk
- tested against pynfs 4.1 server, submitting ipv6 support patch to pynfs
- tested with IPv6 disabled, it compiles cleanly and relies on rpc_pton to
refuse to accept IPv6 addresses
