Subject: kabi fix for sunrpc-use-after-free-in-svc_process_common.patch
Patch-mainline: never, kabi
References: bsc#1119946 CVE-2018-16884

'struct svc_rqst' is visible to modules -  auth_gss in particular,
so changes must be hidden for kabi stability.
The new field is not useful to an auth module, so hiding it
won't hurt.
