new primitive: d_exact_alias(dentry, inode). If there is an unhashed dentry with the same name/parent and given inode, rehash, grab and return it. Otherwise, return NULL.

When LAYOUTGET gets NFS4ERR_DELAY, we currently will wait 15s before retrying the call. That is a _very_ long time, so add a timeout value to struct nfs4_layoutget and pass nfs4_async_handle_error a pointer to it.

The xattr_handler operations are currently all passed a file system specific flags value which the operations can use to disambiguate between different handlers; some file systems use that to distinguish the xattr namespace, for example. In some oprations, it would be useful to also have access to the handler prefix. To allow that, pass a pointer to the handler to operations instead of the flags value alone.

When the client goes to return a delegation, it should always update any nfs4_state currently set up to use that delegation stateid to instead use the open stateid. It already does do this in some cases, particularly in the state recovery code, but not currently when the delegation is voluntarily returned (e.g. in advance of a RENAME). This causes the client to try to continue using the delegation stateid after the DELEGRETURN, e.g. in LAYOUTGET. Set the nfs4_state back to using the open stateid in nfs4_open_delegation_recall, just before clearing the NFS_DELEGATED_STATE bit.

When a read delegation is being recalled, and we're reclaiming the cached opens, we need to make sure that we only reclaim read-only modes. A previous attempt to do this, relied on retrieving the delegation type from the nfs4_opendata structure. Unfortunately, as Kinglong pointed out, this field can only be set when performing reboot recovery. Furthermore, if we call nfs4_open_recover(), then we end up clobbering the state->flags for all modes that we're not recovering... The fix is to have the delegation recall code pass this information to the recovery call, and then refactor the recovery code so that nfs4_open_delegation_recall() does not need to call nfs4_open_recover().
