Becoming "writer" on an IPSQ 1078e11c3f44Smeem * ensures that no other threads can become "writer" on any IPSQs sharing that 1079e11c3f44Smeem * IPSQ's xop until the writer thread is done. 1080e11c3f44Smeem * 1081e11c3f44Smeem * Each phyint points to one IPSQ that remains fixed over the phyint's life. 1082e11c3f44Smeem * Each IPSQ points to one xop that can change over the IPSQ's life. If a 1083e11c3f44Smeem * phyint is *not* in an IPMP group, then its IPSQ will refer to the IPSQ's 1084e11c3f44Smeem * "own" xop (ipsq_ownxop). If a phyint *is* part of an IPMP group, then its 1085e11c3f44Smeem * IPSQ will refer to the "group" xop, which is shorthand for the xop of the 1086e11c3f44Smeem * IPSQ of the IPMP meta-interface's phyint. Thus, all phyints that are part 1087e11c3f44Smeem * of the same IPMP group will have their IPSQ's point to the group xop, and 1088e11c3f44Smeem * thus becoming "writer" on any phyint in the group will prevent any other 1089e11c3f44Smeem * writer on any other phyint in the group. All IPSQs sharing the same xop 1090e11c3f44Smeem * are chained together through ipsq_next (in the degenerate common case, 1091e11c3f44Smeem * ipsq_next simply refers to itself). Note that the group xop is guaranteed 1092e11c3f44Smeem * to exist at least as long as there are members in the group, since the IPMP 1093e11c3f44Smeem * meta-interface can only be destroyed if the group is empty. 1094e11c3f44Smeem * 1095e11c3f44Smeem * Incoming exclusive operation requests are enqueued on the IPSQ they arrived 1096e11c3f44Smeem * on rather than the xop. This makes switching xop's (as would happen when a 1097e11c3f44Smeem * phyint leaves an IPMP group) simple, because after the phyint leaves the 1098e11c3f44Smeem * group, any operations enqueued on its IPSQ can be safely processed with 1099e11c3f44Smeem * respect to its new xop, and any operations enqueued on the IPSQs of its 1100e11c3f44Smeem * former group can be processed with respect to their existing group xop. 1101e11c3f44Smeem * Even so, switching xops is a subtle dance; see ipsq_dq() for details. 1102e11c3f44Smeem * 1103e11c3f44Smeem * An IPSQ's "own" xop is embedded within the IPSQ itself since they have have 1104e11c3f44Smeem * identical lifetimes, and because doing so simplifies pointer management. 1105e11c3f44Smeem * While each phyint and IPSQ point to each other, it is not possible to free 1106e11c3f44Smeem * the IPSQ when the phyint is freed, since we may still *inside* the IPSQ 1107e11c3f44Smeem * when the phyint is being freed.
