Subject: [PATCH 1/5] KEYS: Increase root_maxkeys and root_maxbytes sizes

From: Steve Dickson <stevedredhatcom>

Now that NFS client uses the kernel key ring facility to store the NFSv4
id/gid mappings, the defaults for root_maxkeys and root_maxbytes need to be
substantially increased.

These values have been soak tested:
