Subject: [PATCH 08/21] fs: cifs: Replace CURRENT_TIME with ktime_get_real_ts()
Date: Wed,  8 Jun 2016 22:04:52 -0700
Message-ID: <1465448705-25055-9-git-send-email-deepa.kernel@gmail.com> (raw)
In-Reply-To: <1465448705-25055-1-git-send-email-deepa.kernel@gmail.com>

This is in preparation for the patch that transitions
vfs timestamps to use 64 bit time and hence make them
y2038 safe.

CURRENT_TIME macro will be deleted before merging the
aforementioned patch.

Filesystem times will use current_fs_time() instead of
CURRENT_TIME.
Use ktime_get_real_ts() here as this is not filesystem time.
ktime_get_real_ts() returns the timestamp in ns which can
be used to calculate network time for NTLMv2 authentication
timestamp.

All cifs timestamps currently use timespec internally.
This timestamp can also be transitioned into using
timespec64 when all other timestamps for cifs is transitioned
to use timespec64.
