      There are cases that layout version has not been transferred to OST object after mirror extend/split/resync which makes following sync hang.

      OFD will compare the layout version from client with on-disk object's in ofd_verify_layout_version(), as the client's version increased with mirror extend/split/resync, the sync IO will keep loop with EINPROGRESS reply from the OFD.
