From 56e714312e7dbd6bb83b2f78d3ec19a404c7649f Mon Sep 17 00:00:00 2001 From: Tina Ruchandani Date: Thu, 16 Mar 2017 16:27:46 +0000 Subject: afs: Prevent callback expiry timer overflow get_seconds() returns real wall-clock seconds. On 32-bit systems this value will overflow in year 2038 and beyond. This patch changes afs_vnode record to use ktime_get_real_seconds() instead, for the fields cb_expires and cb_expires_at.
