From efeda80da38d0b4afd77a12bd4a44f657567d26c Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Wed, 5 Feb 2020 09:01:54 -0500 Subject: NFSv4: Fix revalidation of dentries with delegations If a dentry was not initially looked up while we were holding a delegation, then we do still need to revalidate that it still holds the same name. If there are multiple hard links to the same file, then all the hard links need validation.
