From 188b95dd8ecb02dd6c6e5534cddc5a89aa4e2852 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Thu, 18 Oct 2007 03:05:21 -0700 Subject: NFS: if ATTR_KILL_S*ID bits are set, then skip mode change If the ATTR_KILL_S*ID bits are set then any mode change is only for clearing the setuid/setgid bits. For NFS, skip the mode change and let the server handle it. Signed-off-by: Jeff Layton Cc: Trond Myklebust Cc: "J.
