    Description

      Currently when creating/opening a file, we do not let the client hash the name so next access (frequently stat?) goes to talk on the MDS. This is also seen in various tests like mdtest.

      We should consider returning more bits from the open call. This is in addition to LU-10948 that handles similar situation for recurring non-creating opens.
