      Description

      This is something Li Xi suggested a few years ago - It should be possible to do lockahead automatically by tracking the write pattern (like LU-12468) and using server-side contention checking to tell the client when to do this.  (Lockahead is currently only usable by clients which know to ask for it.)

      This should let clients get good performance when strided writes with non-stripe aligned i/o, as long as the i/o is page aligned (LDLM & OSC locks are at page granularity).
