      Trying to investigate an idea that client side locks are not needed for direct i/o, formally, there is no client cache to protect, and client locks are expanded at server to the maximum extent while server-side locks are not (part of lock-ahead patch).

      The improvement was initially implemented for Luste-1.8 (https://bugzilla.lustre.org/show_bug.cgi?id=18801) and lost during client re-write (CLIO).
