[PATCH 01/10] fs: Add current_fs_time_sec() function

Show all headers | View raw

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.
