Becoming "writer" on an IPSQ 1039e11c3f44Smeem * ensures that no other threads can become "writer" on any IPSQs sharing that 1040e11c3f44Smeem * IPSQ's xop until the writer thread is done. 1041e11c3f44Smeem * 1042e11c3f44Smeem * Each phyint points to one IPSQ that remains fixed over the phyint's life. 1043e11c3f44Smeem * Each IPSQ points to one xop that can change over the IPSQ's life. If a 1044e11c3f44Smeem * phyint is *not* in an IPMP group, then its IPSQ will refer to the IPSQ's 1045e11c3f44Smeem * "own" xop (ipsq_ownxop). If a phyint *is* part of an IPMP group, then its 1046e11c3f44Smeem * IPSQ will refer to the "group" xop, which is shorthand for the xop of the 1047e11c3f44Smeem * IPSQ of the IPMP meta-interface's phyint. Thus, all phyints that are part 1048e11c3f44Smeem * of the same IPMP group will have their IPSQ's point to the group xop, and 1049e11c3f44Smeem * thus becoming "writer" on any phyint in the group will prevent any other 1050e11c3f44Smeem * writer on any other phyint in the group. All IPSQs sharing the same xop 1051e11c3f44Smeem * are chained together through ipsq_next (in the degenerate common case, 1052e11c3f44Smeem * ipsq_next simply refers to itself). Note that the group xop is guaranteed 1053e11c3f44Smeem * to exist at least as long as there are members in the group, since the IPMP 1054e11c3f44Smeem * meta-interface can only be destroyed if the group is empty. 1055e11c3f44Smeem * 1056e11c3f44Smeem * Incoming exclusive operation requests are enqueued on the IPSQ they arrived 1057e11c3f44Smeem * on rather than the xop. This makes switching xop's (as would happen when a 1058e11c3f44Smeem * phyint leaves an IPMP group) simple, because after the phyint leaves the 1059e11c3f44Smeem * group, any operations enqueued on its IPSQ can be safely processed with 1060e11c3f44Smeem * respect to its new xop, and any operations enqueued on the IPSQs of its 1061e11c3f44Smeem * former group can be processed with respect to their existing group xop. 1062e11c3f44Smeem * Even so, switching xops is a subtle dance; see ipsq_dq() for details. 1063e11c3f44Smeem * 1064e11c3f44Smeem * An IPSQ's "own" xop is embedded within the IPSQ itself since they have have 1065e11c3f44Smeem * identical lifetimes, and because doing so simplifies pointer management. 1066e11c3f44Smeem * While each phyint and IPSQ point to each other, it is not possible to free 1067e11c3f44Smeem * the IPSQ when the phyint is freed, since we may still *inside* the IPSQ 1068e11c3f44Smeem * when the phyint is being freed.
