[PATCH 4.4 64/93] pNFS/flexfiles: Fix layoutcommit after a commit to DS

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>

commit c001c87a63aa2f35358e33eb05e45e4cbcb34f54 upstream.

We should always do a layoutcommit after commit to DS, except if
the layout segment we're using has set FF_FLAGS_NO_LAYOUTCOMMIT.

Fixes: d67ae825a59d ("pnfs/flexfiles: Add the FlexFile Layout Driver")
