Merge branch 'for-next' of git://git.samba.org/sfrench/cifs-2.6

Pull cifs fixes from Steve French:
 "This ncludes various cifs/smb3 bug fixes, mostly for stable as well.

  In the next week I expect that Germano will have some reconnection
  fixes, and also I expect to have the remaining pieces of the snapshot
  enablement and SMB3 ACLs, but wanted to get this set of bug fixes in"

* 'for-next' of git://git.samba.org/sfrench/cifs-2.6:
  cifs_get_root shouldn't use path with tree name
  Fix default behaviour for empty domains and add domainauto option
  cifs: use %16phN for formatting md5 sum
  cifs: Fix smbencrypt() to stop pointing a scatterlist at the stack
  CIFS: Fix a possible double locking of mutex during reconnect
  CIFS: Fix a possible memory corruption during reconnect
