Merge tag '5.4-smb3-fixes' of git://git.samba.org/sfrench/cifs-2.6

Pull cifs updates from Steve French:
 "Various cifs/smb3 fixes (including for share deleted cases) and
  features including improved encrypted read performance, and various
  debugging improvements.

  Note that since I am at a test event this week with the Samba team,
  and at the annual Storage Developer Conference/SMB3 Plugfest test
  event next week a higher than usual number of fixes is expected later
  next week as other features in progress get additional testing and
  review during these two events"
