[PATCH v3 17/24] fs: ocfs2: Replace CURRENT_TIME with ktime_get_real_seconds()

From: Deepa Dinamani
Date: Sat Jun 25 2016 - 17:41:16 EST


CURRENT_TIME is not y2038 safe.

Use y2038 safe ktime_get_real_seconds() here for timestamps.

struct heartbeat_block's hb_seq and deletetion time are already
64 bits wide and accommodate times beyond y2038.
