From 38478b24e37587f1c4fedf8ac070ca54f052ed28 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Thu, 25 May 2006 01:40:57 -0400 Subject: NFS: More page cache revalidation fixups Whenever the directory changes, we want to make sure that we always invalidate its page cache. Fix up update_changeattr() and nfs_mark_for_revalidate() so that they do so.
