| Date | 2016-06-20 02:50 +0200 |

The current_fs_time() api is being changed to use vfs
struct inode* as an argument instead of struct super_block*.
Set the new mds client request r_stamp field using
ktime_get_real_ts() instead of using current_fs_time().
Also, since r_stamp is used as mtime on the server, use
timespec_trunc() to truncate the timestamp, using the right
granularity from the superblock.
This api will be transitioned to be y2038 safe along
with vfs.
