  NTLM auth and sign - Use appropriate server challenge
  cifs: add kfree() on error path
  NTLM auth and sign - minor error corrections and cleanup
  NTLM auth and sign - Use kernel crypto apis to calculate hashes and smb signatures
  NTLM auth and sign - Define crypto hash functions and create and send keys needed for key exchange
  cifs: cifs_convert_address() returns zero on error
  NTLM auth and sign - Allocate session key/client response dynamically
  cifs: update comments - [s/GlobalSMBSesLock/cifs_file_list_lock/g]
  cifs: eliminate cifsInodeInfo->write_behind_rc (try #6)
  [CIFS] Fix checkpatch warnings and bump cifs version number
  cifs: wait for writeback to complete in cifs_flush
