Subject: [PATCH] NFS: Remove an incorrect revalidation in
nfs4_update_changeattr_locked()

In nfs4_update_changeattr_locked(), we don't need to set the NFS_INO_REVAL_PAGECACHE flag, because we already know the value of the change attribute, and we're already flagging the size. In fact, this forces us to revalidate the change attribute a second time for no good reason.
This extra flag appears to have been introduced as part of the xattr feature, when update_changeattr_locked() was converted for use by the xattr code.
