From 9cdd1d3f1a8cea9cfe7953f45fae9ff51c37afa3 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Fri, 16 Dec 2016 18:04:47 -0500 Subject: [PATCH] NFS: Only look at the change attribute cache state in nfs_weak_revalidate() Just like in nfs_check_verifier(), we want to use nfs_mapping_need_revalidate_inode() to check our knowledge of the change attribute is up to date.
