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."

* 'for-linus' of git://git.samba.org/sfrench/cifs-2.6:
  CIFS: Fix a deadlock when a file is reopened
  CIFS: Reopen the file if reconnect durable handle failed
  [CIFS] Fix minor endian error in durable handle patch series
  CIFS: Reconnect durable handles for SMB2
  CIFS: Make SMB2_open use cifs_open_parms struct
  CIFS: Introduce cifs_open_parms struct
  CIFS: Request durable open for SMB2 opens
  CIFS: Simplify SMB2 create context handling
  CIFS: Simplify SMB2_open code path
  CIFS: Respect create_options in smb2_open_file
  CIFS: Fix lease context buffer parsing
  [CIFS] use sensible file nlink values if unprovided
  Limit allocation of crypto mechanisms to dialect which requires
