++notifying process it will be replaced. The supervisor can also add an FD, and
++respond atomically by using the ``SECCOMP_ADDFD_FLAG_SEND`` flag and the return

++ * a) lock_list in the ->locks_after list of A, whose ->class is B and

++ * b) lock_list in the ->locks_before list of B, whose ->class is A
++ * and ->links_to is B. In this case, we can say the lock_list is
++ * "B <- A" (bacwards case).
++ *
++ * The ->trace of both a) and b) point to the call trace where B was
++ * acquired with A held.
++ *
++ * 2) A "helper" lock_list is introduced during BFS, this lock_list doesn't
++ * represent a certain lock dependency, it only provides an initial entry
++ * for BFS. For example, BFS may introduce a "helper" lock_list whose
++ * ->class is A, as a result BFS will search all dependencies starting with
++ * A, e.g. A -> B or A -> C.
++ *
++ * The notation of a forwards helper lock_list is like "-> A", which means
++ * we should search the forwards dependencies starting with "A", e.g A -> B
++ * or A -> C.
++ *
++ * The notation of a bacwards helper lock_list is like "<- B", which means
++ * we should search the backwards dependencies ending with "B", e.g.
