[PATCH] knfsd: lockd: introduce nsm_handle
This patch introduces the nsm_handle, which is shared by all nlm_host objects
referring to the same client.
With this patch applied, all nlm_hosts from the same address will share the
same nsm_handle. A future patch will add sharing by name.
Note: this patch changes h_name so that it is no longer guaranteed to be an IP
address of the host. When the host represents an NFS server, h_name will be
the name passed in the mount call. When the host represents a client, h_name
will be the name presented in the lock request received from the client. A
h_name is only used for printing informational messages, this change should
not be significant.
