v6: - add patch 1/2 to make sparc architecture happy. [Sam] - close created sessions previousely when rekeying. - convert the priority of virtio crypto algs from 4001 to 501 which is enough. v5: - add comments for algs_lock and table_lock. [Stefan] - use kzfree instead of kfree for key material security. [Stefan] - drop unnecessary spin_lock for struct virtio_crypto_ablkcipher_ctx. -
