Subject: [PATCH 10/21] fs: f2fs: Use ktime_get_real_seconds for sit_info times
Date: Wed,  8 Jun 2016 22:04:54 -0700
Message-ID: <1465448705-25055-11-git-send-email-deepa.kernel@gmail.com> (raw)
In-Reply-To: <1465448705-25055-1-git-send-email-deepa.kernel@gmail.com>

CURRENT_TIME_SEC is not y2038 safe.

Replace use of CURRENT_TIME_SEC with ktime_get_real_seconds
in segment timestamps used by GC algorithm including the
segment mtime timestamps.
