From: Trond Myklebust Date: Sun, 30 Sep 2007 15:13:17 -0400 NFS: Remove bogus check of cache_change_attribute in nfs_update_inode Remove the bogus 'data_stable' check in nfs_update_inode. The cache_change_attribute tells you if the directory changed on the server, and should have nothing to do with the file length.
