Herbert Xu 048545d9fc crypto: api - Use work queue in crypto_destroy_instance ... [ Upstream commit 9ae4577bc0 ] The function crypto_drop_spawn expects to be called in process context. However, when an instance is unregistered while it still has active users, the last user may cause the instance to be freed in atomic context. Fix this by delaying the freeing to a work queue.
