Subject: [PATCH 00/12] KEYS: Use preparsing in most key types


Here are a set of patches that make all but encrypted and trusted keys use
preparsing.  Unfortunately, encrypted and trusted keys incorrectly use the
update op to alter a key, so other changes will need to be made for them.

These changes permit payload parsing when instantiating or updating a key to be
done before locks are taken and to determine the amount of quota that will be
required in advance.  The latter will make it possible to do LRU discard before
any locks are taken.

They can be found here also:

      KEYS: Provide a generic instantiation function
      KEYS: struct key_preparsed_payload should have two payload pointers
      KEYS: Allow expiry time to be set when preparsing a key
      KEYS: Call ->free_preparse() even after ->preparse() returns an error
      KEYS: user: Use key preparsing
      KEYS: Ceph: Use key preparsing
      KEYS: Ceph: Use user_match()
      KEYS: DNS: Use key preparsing
      KEYS: RxRPC: Use key preparsing
      KEYS: big_key: Use key preparsing
