    [CRYPTO] Allow multiple implementations of the same algorithm · 5cb1454b
    Herbert Xu authored
    This is the first step on the road towards asynchronous support in
    the Crypto API.  It adds support for having multiple crypto_alg objects
    for the same algorithm registered in the system.
    For example, each device driver would register a crypto_alg object
    for each algorithm that it supports.  While at the same time the
    user may load software implementations of those same algorithms.
    Users of the Crypto API may then select a specific implementation
    by name, or choose any implementation for a given algorithm with
    the highest priority.
    The priority field is a 32-bit signed integer.  In future it will be
    possible to modify it from user-space.
    This also provides a solution to the problem of selecting amongst
    various AES implementations, that is, aes vs. aes-i586 vs. aes-padlock.
