/*
* 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
* userspace 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 userspace 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.
