boot_time is represented as a struct timespec.
struct timespec and CURRENT_TIME are not y2038 safe.
Overall, the plan is to use timespec64 for all internal
kernel representation of timestamps.
CURRENT_TIME will also be removed.
Use struct timespec64 to represent boot_time.
And, ktime_get_real_ts64() for the boot_time value.
boot_time is used to construct the nfs client boot verifier.
This will now wrap in 2106 instead of 2038 on 32-bit systems.
The server only relies on the value being persistent until
reboot so the wrapping should be fine.
