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

Pull cifs fixes from Steve French:
 "Fixes for 4 cifs bugs, including a reconnect problem, a problem
  parsing responses to SMB2 open request, and setting nlink incorrectly
  to some servers which don't report it properly on the wire.  Also
  improves data integrity on reconnect with series from Pavel which adds
  durable handle support for SMB2."
