    [CRYPTO] digest: Added user API for new hash type · 055bcee3
    Herbert Xu authored
    The existing digest user interface is inadequate for support asynchronous
    operations.  For one it doesn't return a value to indicate success or
    failure, nor does it take a per-operation descriptor which is essential
    for the issuing of requests while other requests are still outstanding.
    
    This patch is the first in a series of steps to remodel the interface
    for asynchronous operations.
    
    For the ease of transition the new interface will be known as "hash"
    while the old one will remain as "digest".
    
    This patch also changes sg_next to allow chaining.
