Hi all, The patchsets add LAYOUTSTATS support to flexfiles. LAYOUTSTATS are sent every minute if IO is still happening upon a file. One limitation is that at most 4 LAYOUTSTATS calls are permitted in a compound. Had to send multiple LAYOUTSTATS operations per compound because OP_LAYOUTSTATS requires stateid and deviceid as its arguments, which makes it a per-file per-deviceid call. Cheers, Tao v1->v2 Changelog: 1. don't reset IO statistics upon LAYOUTSTATS reply per latest NFS42 draft. 2. update flexfiles xdr to match latetst flexfiles draft. 3. address Jeff's comments and add his reviewed-by line.
