   4 Subject: smb: fix secondary channel creation issue with kerberos by populating hostname when adding channels
   5
   6 From: Bharath SM <bharathsm@microsoft.com>
   7
   8 commit 306cb65bb0cb243389fcbd0a66907d5bdea07d1e upstream.
   9
  10 When mounting a share with kerberos authentication with multichannel
  11 support, share mounts correctly, but fails to create secondary
  12 channels. This occurs because the hostname is not populated when
  13 adding the channels. The hostname is necessary for the userspace
  14 cifs.upcall program to retrieve the required credentials and pass
  15 it back to kernel, without hostname secondary channels fails
  16 establish.
