  "message": "[CRYPTO] chainiv: Avoid lock spinning where possible\n\nThis patch makes chainiv avoid spinning by postponing requests on lock\ncontention if the user allows the use of asynchronous algorithms.  If\na synchronous algorithm is requested then we behave as before.\n\nThis should improve IPsec performance on SMP when two CPUs attempt to\ntransmit over the same SA.  Currently one of them will spin doing nothing\nwaiting for the other CPU to finish its encryption.  This patch makes it\npostpone the request and get on with other work.\n\nIf only one CPU is transmitting for a given SA, then we will process\nthe request synchronously as before.\n\nSigned-off-by: Herbert Xu \u003cherbert@gondor.apana.org.au\u003e\n",
