afs: Prevent callback expiry timer overflow
[ Upstream commit 56e714312e7dbd6bb83b2f78d3ec19a404c7649f ]
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.
