From a5cddc885b99458df963a75abbe0b40cbef56c48 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Mon, 12 May 2014 18:10:58 -0400 Subject: nfsd4: better reservation of head space for krb5 RPC_MAX_AUTH_SIZE is scattered around several places. Better to set it once in the auth code, where this kind of estimate should be made. And while we're at it we can leave it zero when we're not using krb5i or krb5p. Signed-off-by: J.
