Hi Steve,

Follow a series with dfs fixes and improvements.

  - correctly handle different charsets when passing around DFS paths
    by converting them all to a default enconding in cache (utf8).

  - keep SMB sessions alive as long as dfs mounts are actives in order
    to refresh cached entries by using IPC tcons.

  - set a mininum of 2 minutes for refreshing cached entries

  - fix broken hash of case sensitive DFS paths

  - skip unnecessary tree disconnect of IPCs when shutting down SMB
    sessions (it didn't even work before).

  - do not share tcp servers when mounting dfs shares because they may
    failover to completely different targets (use nosharesock).

Paulo Alcantara (7):
  cifs: do not send tree disconnect to ipc shares
  cifs: get rid of @noreq param in __dfs_cache_find()
  cifs: keep referral server sessions alive
  cifs: handle different charsets in dfs cache
  cifs: fix path comparison and hash calc
  cifs: set a minimum of 2 minutes for refreshing dfs cache
  cifs: do not share tcp servers with dfs mounts
