From 400f26b542e86995662a0cc5483656b7b1f42af6 Mon Sep 17 00:00:00 2001 From: Simo Sorce Date: Fri, 25 May 2012 18:09:53 -0400 Subject: SUNRPC: conditionally return endtime from import_sec_context We expose this parameter for a future caller. It will be used to extract the endtime from the gss-proxy upcall mechanism, in order to set the rsc cache expiration time. Signed-off-by: Simo Sorce Signed-off-by: J.
