NFSv4: Don't invalidate inode attributes on delegation return
commit 00c94ebec5925593c0377b941289224469e72ac7 upstream. There is no need to declare attributes such as the ctime, mtime and block size invalid when we're just returning a delegation, so it is inappropriate to call nfs_post_op_update_inode_force_wcc(). Instead, just call nfs_refresh_inode() after faking up the change attribute. We know that the GETATTR op occurs before the DELEGRETURN, so we are safe when doing this. Fixes: 0bc2c9b4dca9 ("NFSv4: Don't discard the attributes returned by asynchronous DELEGRETURN") Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
