From dd1db2dedc4f6ad736fbba5aa6ecfe6e7c8ee0f4 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Thu, 16 Oct 2008 19:27:12 -0400 Subject: [PATCH] cifs: don't use CREATE_DELETE_ON_CLOSE in cifs_rename_pending_delete cifs: don't use CREATE_DELETE_ON_CLOSE in cifs_rename_pending_delete CREATE_DELETE_ON_CLOSE apparently has different semantics than when you set the DELETE_ON_CLOSE bit after opening the file. Setting it in the open says "delete this file as soon as this filehandle is closed". That's not what we want for cifs_rename_pending_delete. Don't set this bit in the CreateFlags. Experimentation shows that setting this flag in the SET_FILE_INFO call has no effect.
