Merge tag '5.13-rc-smb3-part2' of git://git.samba.org/sfrench/cifs-2.6

Pull cifs updates from Steve French:
 "Ten CIFS/SMB3 changes - including two marked for stable - including
  some important multichannel fixes, as well as support for handle
  leases (deferred close) and shutdown support:

   - some important multichannel fixes

   - support for handle leases (deferred close)

   - shutdown support (which is also helpful since it enables multiple
     xfstests)

   - enable negotiating stronger encryption by default (GCM256)

   - improve wireshark debugging by allowing more options for root to
     dump decryption keys

  SambaXP and the SMB3 Plugfest test event are going on now so I am
  expecting more patches over the next few days due to extra testing
  (including more multichannel fixes)"
