From 2f86e0919a02d61ed2350c07f383e5542b904289 Mon Sep 17 00:00:00 2001 From: Deepa Dinamani Date: Sat, 1 Oct 2016 16:46:26 -0700 Subject: fs: nfs: Make nfs boot time y2038 safe boot_time is represented as a struct timespec. struct timespec and CURRENT_TIME are not y2038 safe. Overall, the plan is to use timespec64 and ktime_t for all internal kernel representation of timestamps. CURRENT_TIME will also be removed. boot_time is used to construct the nfs client boot verifier. Use ktime_t to represent boot_time and ktime_get_real() for the boot_time value. Following Trond's request https://lkml.org/lkml/2016/6/9/22 , use ktime_t instead of converting to struct timespec64. Use higher and lower 32 bit parts of ktime_t for the boot verifier. Use the lower 32 bit part of ktime_t for the authsys_parms stamp field.
