This is in preparation for the series that transitions
filesystem timestamps to use 64 bit time and hence make
them y2038 safe.
The function is meant to replace CURRENT_TIME_SEC macro.
The macro CURRENT_TIME_SEC does not represent filesystem times
correctly as it cannot perform range checks.
current_fs_time_sec() will be extended to include these.
CURRENT_TIME_SEC is also not y2038 safe. current_fs_time_sec()
will be transitioned to use 64 bit time along with vfs in a
separate series.
The function is inline for now to maintain similar performance
to that of the macro.
The function takes super block as a parameter to allow for
future range checking of filesystem timestamps.
