Stephan Mueller 7d2c3f54e6 crypto: af_alg - remove locking in async callback ... The code paths protected by the socket-lock do not use or modify the socket in a non-atomic fashion. The actions pertaining the socket do not even need to be handled as an atomic operation. Thus, the socket-lock can be safely ignored. This fixes a bug regarding scheduling in atomic as the callback function may be invoked in interrupt context. In addition, the sock_hold is moved before the AIO encrypt/decrypt operation to ensure that the socket is always present. This avoids a tiny race window where the socket is unprotected and yet used by the AIO operation. Finally, the release of resources for a crypto operation is moved into a common function of af_alg_free_resources.
