Merge branch 'for-next' of git://git.samba.org/sfrench/cifs-2.6 

Pull SMB3 fixes from Steve French:
 "Some small bug fixes as well as SMB2.1/SMB3 enablement for DFS (global
  namespace) which previously was only enabled for CIFS"

* 'for-next' of git://git.samba.org/sfrench/cifs-2.6:
  smb2: Enforce sec= mount option
  CIFS: Fix sparse warnings
  CIFS: implement get_dfs_refer for SMB2+
  CIFS: use DFS pathnames in SMB2+ Create requests
  CIFS: set signing flag in SMB2+ TreeConnect if needed
  CIFS: let ses->ipc_tid hold smb2 TreeIds
  CIFS: add use_ipc flag to SMB2_ioctl()
  CIFS: add build_path_from_dentry_optional_prefix()
  CIFS: move DFS response parsing out of SMB1 code
  CIFS: Fix possible use after free in demultiplex thread
