Subject: [PATCH] smb3: for kerberos mounts display the credential uid used
Git-commit: 96281b9e46ebb90cefa8b57b11ca40e5ac05f649
Patch-mainline: v5.1-rc1
References: bsc#1144333
For kerberos mounts, the cruid is helpful to display in
/proc/mounts in order to tell which uid's krb5 cache we
got the ticket for and to tell in the multiuser krb5 case
which local users (uids) we have Kerberos authentic sessions
for.
