From 3bbeeb3c93a961bd01b969dd4395ecac0c09db8d Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Thu, 9 Jul 2009 20:02:50 -0400 Subject: cifs: add and use CIFSSMBUnixSetFileInfo for setattr calls cifs: add and use CIFSSMBUnixSetFileInfo for setattr calls When there's an open filehandle, SET_FILE_INFO is apparently preferred over SET_PATH_INFO. Add a new variant that sets a FILE_UNIX_INFO_BASIC infolevel via SET_FILE_INFO and switch cifs_setattr_unix to use the new call when there's an open filehandle available.
