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

Pull CIFS fixes from Steve French:
 "This includes a set of misc.  cifs fixes (most importantly some byte
  range lock related write fixes from Pavel, and some ACL and idmap
  related fixes from Jeff) but also includes the SMB2.02 dialect
  enablement, and a key fix for SMB3 mounts.

  Default authentication upgraded to ntlmv2 for cifs (it was already
  ntlmv2 for smb2)"

* 'for-next' of git://git.samba.org/sfrench/cifs-2.6: (43 commits)

  cifs: deal with id_to_sid embedded sid reply corner case
  cifs: fix hardcoded default security descriptor length
  cifs: extra sanity checking for cifs.idmap keys
  cifs: avoid extra allocation for small cifs.idmap keys
  cifs: simplify id_to_sid and sid_to_id mapping code
  CIFS: Fix possible data coherency problem after oplock break to None
  CIFS: Do not permit write to a range mandatory locked with a read lock
  cifs: rename cifs_readdir_lookup to cifs_prime_dcache and make it void return
  cifs: Add CONFIG_CIFS_DEBUG and rename use of CIFS_DEBUG
