    Description

      Both ext4 and ZFS allow storing the file creation time in the on-disk inode, and the new statx() API allows returning it to userspace, but as yet we do not have any mechanism to send it from the servers to the client.

      Add fields into struct mdt_body and an OBD_MD_FLCRTIME flag to allow it to be requested and returned. There probably is no value to get it from the OSTs or in the LVB since those objects are precreated and their creation time is not accurate.
