Subject: [RFC v2a 07/12] fs: btrfs: Use vfs_time data type for btrfs_update_time()
Date: Fri, 12 Feb 2016 01:36:01 -0800	[thread overview]
Message-ID: <1455269766-2994-8-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.

This is set as a vfs callback function for inode operations.
This accepts inode timestamp as an argument.
And, needs to switch to 64 bit time representation along with vfs.
