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

Pull CIFS updates from Steve French:
 "This patchset is the final section of the SMB2.1 support merge for
  cifs.ko.  It also includes improvements to the cifs socket handling
  from Jeff, and also fixes a few cifs bug fixes.  It adds SMB2 support
  for file and inode operations as well as moves some existing cifs code
  to use ops server struct of protocol specific callbacks.

  Most of this code is SMB2 specific.  When enabled SMB2.1 does pass
  various functional tests including most of the connectathon test
  suite, For SMB2.1, Connectathon test 4 and some related tests fail due
  to not updating mode bits remotely (cifsacl support where mode bits
  are approximated with the cifs acl is not enable for smb2), and test8
  (symlink) support is not completed for SMB2 yet (note that we will
  likely have a "Unix Extensions" eventually, at least for Samba, so in
  the long run posix locks won't have to be emulated when mounting Linux
  to Linux, but for most NAS and for Windows mounts posix lock emulation
  will still used for SMB2 in a similar fashion as we do for cifs).

  SMB2.1 dialect is supported.  Although additional fixes to enable smb2
  (the original smb2.02) dialect and to add various optional features of
  the smb3 dialect are expected to be added in the future as testing
  progresses, currently mounting with the "vers=2.1" is supported (in
  order to mount using SMB2.1 to servers like Samba 4, and Windows 7,
  Windows 2008R2)."
