    Description

      Since kernel commit v4.6-rc3-29-g6192269 there is a new ->iterate_shared() file operation for reading directories with a shared lock on the client. We should change over the llite client to use the ->iterate_shared() method to improve directory access concurrency on the client.

      There is already a HAVE_ITERATE_SHARED configure check that can be used to detect support for this functionality.
