This is in preparation for the patch that transitions vfs timestamps to use 64 bit time and hence make them y2038 safe.
CURRENT_TIME macro will be deleted before merging the aforementioned patch.
Filesystem times will use current_fs_time() instead of CURRENT_TIME. Use ktime_get_real_ts() here as this is not filesystem time. ktime_get_real_ts() returns the timestamp in ns which can be used to calculate network time for NTLMv2 authentication timestamp.
All cifs timestamps currently use timespec internally. This timestamp can also be transitioned into using timespec64 when all other timestamps for cifs is transitioned to use timespec64.
