      Description

      This work tracked the MDS handling of PFL layout object initialization.

      • Initialize the OST objects of the 1st component of┬áthe PFL when its data are┬ábeing created or its layout being set.
      • When the client tries to write beyond OST-object-initialized extent range, it will issue an IT_LAYOUT_MOD intent lock RPC, indicating the end offset of the write range, MDS needs to handle this RPC to allocate all OST objects of components covering this range.
      • MDS also needs to handle the replay of IT_LAYOUT_MOD RPC, which contains the current layout objects which the client knows, so that MDS won't allocate those OST objects again.
