Hi Steve,

Follow a series of bugfixes that were mostly found by doing some
stress testing over the reconnect paths. I was able to find most of
the issues by hard-coding the DFS cache ttl to 10 seconds which made
it running several times on every reconnect test.

Please review and test.

Paulo Alcantara (7):
  cifs: fix potential race when tree connecting ipc
  cifs: fix potential use-after-free bugs in TCP_Server_Info::hostname
  cifs: protect session status check in smb2_reconnect()
  cifs: protect access of TCP_Server_Info::{origin,leaf}_fullpath
  cifs: print smb3_fs_context::source when mounting
  cifs: avoid potential races when handling multiple dfs tcons
  cifs: fix sharing of DFS connections
