25 Simply put, an NFSv4 server creates a lease for each NFSv4 client.
27 the lease for that client.
30 While a lease remains valid, the server holding that lease
33 If a client stops renewing its lease (for example, if it crashes),
51 they can associate the client with its lease. Each client's
65 principal to authorize subsequent lease modification operations
87 Protecting NFSv4 lease state
91 assign a unique lease to each client. Under this scheme, there are
93 referred to as "lease stealing".
