/*
 * Generic asynchronous request/response support
 *
 * Many of the APIs supported by HDD require a call to SME to
 * perform an action or to retrieve some data.  In most cases SME
 * performs the operation asynchronously, and will execute a provided
 * callback function when the request has completed.  In order to
 * synchronize this the HDD API allocates a context which is then
 * passed to SME, and which is then, in turn, passed back to the
 * callback function when the operation completes.  The callback
 * function then sets a completion variable inside the context which
 * the HDD API is waiting on.  In an ideal world the HDD API would
 * wait forever (or at least for a long time) for the response to be
 * received and for the completion variable to be set.  However in
 * most cases these HDD APIs are being invoked in the context of a
 * user space thread which has invoked either a cfg80211 API or a
 * wireless extensions ioctl and which has taken the kernel rtnl_lock.
 * Since this lock is used to synchronize many of the kernel tasks, we
 * do not want to hold it for a long time.  In addition we do not want
 * to block user space threads (such as the wpa supplicant's main
 * thread) for an extended time.  Therefore we only block for a short
 * time waiting for the response before we timeout.  This means that
 * it is possible for the HDD API to timeout, and for the callback to
 * be invoked afterwards.  In order for the callback function to
 * determine if the HDD API is still waiting, a magic value is also
 * stored in the shared context.  Only if the context has a valid
 * magic will the callback routine do any work.  In order to further
 * synchronize these activities a spinlock is used so that if any HDD
 * API timeout coincides with its callback, the operations of the two
 * threads will be serialized.
