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.
vfs_time is an abstraction that hides the type of timestamps
across vfs. This is necessary because we want to change the
data types of vfs timestamps to support 64 bit times.
current_fs_time() will change along with vfs timestamp data
type changes.
xfs_vn_update_time() is a .update callback for inode operations
and this needs to change along with vfs inode times.
All the accesses to or from struct inode timestamps and
current_fs_time() are also changed to vfs_time.
