From 40d24704091c8a29a4c99d25670f1996749aea6f Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Mon, 8 Oct 2007 09:24:22 -0400 Subject: [PATCH] NFS: Fix a connectathon regression in NFSv3 and NFSv4 We're failing basic test6 against Linux servers because they lack a correct change attribute. The fix is to assume that we always want to invalidate the readdir caches when we call update_changeattr and/or nfs_post_op_update_inode on a directory.
