From 0bc2c9b4dca9668a236fde48ebb15e5f0735cbff Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Fri, 16 Dec 2016 19:48:09 -0500 Subject: [PATCH] NFSv4: Don't discard the attributes returned by asynchronous DELEGRETURN DELEGRETURN will always carry a reference to the inode except when the latter is being freed, so let's ensure that we always use that inode information to ensure close-to-open cache consistency, even when the DELEGRETURN call is asynchronous.
