* git://git.kernel.org/pub/scm/linux/kernel/git/sfrench/cifs-2.6:
  cifs: when ATTR_READONLY is set, only clear write bits on non-directories
  cifs: remove cifsInodeInfo->inUse counter
  cifs: convert cifs_get_inode_info and non-posix readdir to use cifs_iget
  [CIFS] update cifs version number
  cifs: add and use CIFSSMBUnixSetFileInfo for setattr calls
  cifs: make a separate function for filling out FILE_UNIX_BASIC_INFO
  cifs: rename CIFSSMBUnixSetInfo to CIFSSMBUnixSetPathInfo
  cifs: add pid of initiating process to spnego upcall info
  cifs: fix regression with O_EXCL creates and optimize away lookup
  cifs: add new cifs_iget function and convert unix codepath to use it

hard link detection to use same inode for both.  Do not set
