Todd Kjos 9630fe8839 binder: introduce locking helper functions ... There are 3 main spinlocks which must be acquired in this order: 1) proc->outer_lock : protects most fields of binder_proc, binder_thread, and binder_ref structures. binder_proc_lock() and binder_proc_unlock() are used to acq/rel. 2) node->lock : protects most fields of binder_node. binder_node_lock() and binder_node_unlock() are used to acq/rel 3) proc->inner_lock : protects the thread and node lists (proc->threads, proc->nodes) and all todo lists associated with the binder_proc (proc->todo, thread->todo, proc->delivered_death and node->async_todo). binder_inner_proc_lock() and binder_inner_proc_unlock() are used to acq/rel Any lock under procA must never be nested under any lock at the same level or below on procB. Functions that require a lock held on entry indicate which lock in the suffix of the function name: foo_olocked() : requires node->outer_lock foo_nlocked() : requires node->lock foo_ilocked() : requires proc->inner_lock foo_iolocked(): requires proc->outer_lock and proc->inner_lock foo_nilocked(): requires node->lock and proc->inner_lock Signed-off-by: Todd Kjos <tkjos@google.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2017-07-17 14:48:23 +02:00
