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

Pull CIFS updates from Steve French:
 "Includes a couple of fixes, plus changes to make multiplex identifiers
  easier to read and correlate with network traces, and a set of
  enhancements for SMB3 dialect.  Also adds support for per-file
  compression for both cifs and smb2/smb3 ("chattr +c filename).

  Should have at least one other merge request ready by next week with
  some new SMB3 security features and copy offload support"
