Merge tag '6.6-rc-smb3-client-fixes-part1' of git://git.samba.org/sfrench/cifs-2.6

Pull smb client updates from Steve French:

 - fixes for excessive stack usage

 - multichannel reconnect improvements

 - DFS fix and cleanup patches

 - move UCS-2 conversion code to fs/nls and update cifs and jfs to use
   them

 - cleanup patch for compounding, one to fix confusing function name

 - inode number collision fix

 - reparse point fixes (including avoiding an extra unneeded query on
   symlinks) and a minor cleanup

 - directory lease (caching) improvement
