  32 Subject: autofs:  Fix automounts by using current_real_cred()->uid
  33
  34 Seth Forshee reports that in 4.8-rcN some automounts are failing
  35 because the requesting the automount changed.
  36
  37 The relevant call path is:
  38 follow_automount()
  39     ->d_automount
  40     autofs4_d_automount
  41        autofs4_mount_wait
  42            autofs4_wait
  43
  44 In autofs4_wait wq_uid and wq_gid are set to current_uid() and
  45 current_gid respectively.  With follow_automount now overriding creds
  46 uid that we export to userspace changes and that breaks existing
  47 setups.
  48
  49 To remove the regression set wq_uid and wq_gid from
  50 current_real_cred()->uid and current_real_cred()->gid respectively.
  51 This restores the current behavior as current->real_cred is identical
  52 to current->cred except when override creds are used.
