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.
