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

Pull CIFS update from Steve French:
 "Adds SMB2 rmdir/mkdir capability to the SMB2/SMB2.1 support in cifs.

  I am holding up a few more days on merging the remainder of the
  SMB2/SMB2.1 enablement although it is nearing review completion, in
  order to address some review comments from Jeff Layton on a few of the
  subsequent SMB2 patches, and also to debug an unrelated cifs problem
  that Pavel discovered."

* 'for-next' of git://git.samba.org/sfrench/cifs-2.6:
  CIFS: Add SMB2 support for rmdir
  CIFS: Move rmdir code to ops struct
  CIFS: Add SMB2 support for mkdir operation
  CIFS: Separate protocol specific part from mkdir
  CIFS: Simplify cifs_mkdir call
