From 5bb89b4702e22981445ae01af733a57d1cae2018 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Wed, 25 Mar 2015 14:14:42 -0400 Subject: NFSv4.1/pnfs: Separate out metadata and data consistency for pNFS The LAYOUTCOMMIT operation means different things to different layout types. For blocks and objects, it is both a data and metadata consistency operation. For files and flexfiles, it is only a metadata consistency operation. This patch separates out the 2 cases, allowing the files/flexfiles layout drivers to optimise away the data consistency calls to layoutcommit.
