[PATCH] Keys: Allow in-kernel key requestor to pass auxiliary data to upcaller
The proposed NFS key type uses its own method of passing key requests to
userspace (upcalling) rather than invoking /sbin/request-key. This is
because the responsible userspace daemon should already be running and will
be contacted through rpc_pipefs.
This patch permits the NFS filesystem to pass auxiliary data to the upcall
operation (struct key_type::request_key) so that the upcaller can use a
pre-existing communications channel more easily.
