Subject: [PATCH v4 24/26] fnic: Use time64_t to represent trace timestamps
Date: Sat, 13 Aug 2016 15:48:36 -0700 [thread overview]
Message-ID: <1471128518-24075-25-git-send-email-deepa.kernel@gmail.com> (raw)
In-Reply-To: <1471128518-24075-1-git-send-email-deepa.kernel@gmail.com>
trace timestamps use struct timespec and CURRENT_TIME which
are not y2038 safe.
These timestamps are only part of the trace log on the machine
and are not shared with the fnic.
Replace then with y2038 safe struct timespec64 and
ktime_get_real_ts64(), respectively.
