This is meant to be used by ablk_helper and similar entities to ensure that no reordering is introduced because of requests queued in cryptd with respect to requests being processed in softirq context. The per-cpu queue length limit is also increased to 1000 in line with network limits. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
