#     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)"
