      Description

      In order to make direct inode scanning on the MDT useful, in addition to storing the file size/blocks via LSOM on the MDT, we also need to store the atime/mtime/ctime on the MDT inodes when the LSOM attributes are updated.

      Currently the atime is already lazily updated on the MDS (at close time), but I'm not sure if the final mtime/ctime are sent to the MDS at close time, nor whether they are updated on the MDT inode by the MDS. If this is not being done, then any MDT-only scanning will be broken.
