Merge git://git.kernel.org/pub/scm/linux/kernel/git/sfrench/cifs-2.6

* git://git.kernel.org/pub/scm/linux/kernel/git/sfrench/cifs-2.6:
  [CIFS] pSesInfo->sesSem is used as mutex. Rename it to session_mutex and
  [CIFS] Use unsigned ea length for clarity
  cifs: set server_eof in cifs_fattr_to_inode
  [CIFS] Minor cleanup to EA patch
  cifs: merge CIFSSMBQueryEA with CIFSSMBQAllEAs
  cifs: verify lengths of QueryAllEAs reply
  cifs: increase maximum buffer size in CIFSSMBQAllEAs
  cifs: rename name_len to list_len in CIFSSMBQAllEAs
  cifs: clean up indentation in CIFSSMBQAllEAs
  cifs: add parens around smb_var in BCC macros
