/*
* The framework keeps an internal handle to use in the adaptive
* asynchronous case. This is the case when a client has the
* CRYPTO_ALWAYS_QUEUE bit clear and a provider is used for
* the request. The request is completed in the context of the calling
* thread and kernel memory must be allocated with KM_NOSLEEP.
*
* The framework passes a pointer to the handle in crypto_req_handle_t
* argument when it calls the SPI of the provider. The macros
* KCF_RHNDL() and KCF_SWFP_RHNDL() are used to do this.
*
* When a provider asks the framework for kmflag value via
* crypto_kmflag(9S) we use REQHNDL2_KMFLAG() macro.
