Merge tag '5.6-smb3-fixes-and-dfs-and-readdir-improvements' of git://git.samba.org/sfrench/cifs-2.6

Pull cifs updates from Steve French:
 "Various SMB3/CIFS fixes including four for stable.

   - Improvement to fallocate (enables 3 additional xfstests)

   - Fix for file creation when mounting with modefromsid

   - Add ability to backup/restore dos attributes and creation time

   - DFS failover and reconnect fixes

   - performance optimization for readir

  Note that due to the upcoming SMB3 Test Event (at SNIA SDC next week)
  there will likely be more changesets near the end of the merge window
  (since we will be testing heavily next week, I held off on some
  patches and I expect some additional multichannel patches as well as
  patches to enable some additional xfstests)"
