From 2e18d4d822ea9cc811ea26a880cf2ed47cbf8889 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sun, 26 Jun 2016 18:54:58 -0400 Subject: pNFS: Files and flexfiles always need to commit before layoutcommit So ensure that we mark the layout for commit once the write is done, and then ensure that the commit to ds is finished before sending layoutcommit. Note that by doing this, we're able to optimise away the commit for the case of servers that don't need layoutcommit in order to return updated attributes.
