Subject: [RFC v2a 05/12] fs: cifs: Use vfs_time_get_real_* time functions
Date: Fri, 12 Feb 2016 01:35:59 -0800	[thread overview]
Message-ID: <1455269766-2994-6-git-send-email-deepa.kernel@gmail.com> (raw)
In-Reply-To: <1455269766-2994-1-git-send-email-deepa.kernel@gmail.com>

The VFS inode timestamps are not y2038 safe as they use
struct timespec. These will be changed to use struct timespec64
instead and that is y2038 safe.
But, since the above data type conversion will break the end
file systems, use vfs_time aliases here to access inode times.

Variables in the patch are passed into functions that also take
inode times as argument. Hence, using vfs_time aliases here is
necessary so that they can change to use 64 bit time along with
vfs.
