* use Component::* instead of Server::* * do not use old printf format anymore * do not use old Genode::env()->heap() anymore * avoid pointers where possible, and use references instead * throw away the thread-safe variants of list and AVL tree, nic_bridge became single-threaded in the past * introduce Ram_session_guard instead of Allocator_guard Issue #1987
