    crypto: skcipher - Change default sync geniv on SMP to eseqiv · 0b67fb65
    Herbert Xu authored
    As it stands we use chainiv for sync algorithms and eseqiv for
    async algorithms.  However, when there is more than one CPU
    chainiv forces all processing to be serialised which is usually
    not what you want.  Also, the added overhead of eseqiv isn't that
    Therefore this patch changes the default sync geniv on SMP machines
    to eseqiv.  For the odd situation where the overhead is unacceptable
    then chainiv is still available as an option.
    Note that on UP machines chainiv is still preferred over eseqiv
    for sync algorithms.
