4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: J. Bruce Fields <bfields@xxxxxxxxxx> commit 78794d1890708cf94e3961261e52dcec2cc34722 upstream. Context expiry times are in units of seconds since boot, not unix time. The use of get_seconds() here therefore sets the expiry time decades in the future. This prevents timely freeing of contexts destroyed by client RPC_GSS_PROC_DESTROY requests. We'd still free them eventually (when the module is unloaded or the container shut down), but a lot of contexts could pile up before then.
