From 1a80810fbf238e6dbaaaa5262a76d328ace21376 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 3 Dec 2018 11:30:30 +1100 Subject: SUNRPC: remove machine_cred field from struct auth_cred The cred is a machine_cred iff ->principal is set, so there is no need for the extra flag. There is one case which deserves some explanation. nfs4_root_machine_cred() calls rpc_lookup_machine_cred() with a NULL principal name which results in not getting a machine credential, but getting a root credential instead. This appears to be what is expected of the caller, and is clearly the result provided by both auth_unix and auth_gss which already ignore the flag.
