Modified files: sys/netgraph netgraph.h ng_base.c sys/netgraph/bluetooth/include ng_bluetooth.h Log: Several changes breaking netgraph module ABI collected together: - reorder structures fields (XX_refs) a bit to group fields modified same time together. According to my tests it gives up to 10% SMP performance benefit on real workload due to reduced inter-CPU cache trashing. - change q_flags from long to int as long is not really needed there and it's usage with atomics is argued by some people. - move NGF_WORKQ flag into the separate field q_flags2 as it protected by queue mutex instead of node writer protection used by the rest of flags. - move nd_work queue entry to ng_queue structure to which it is more related and make it STAILQ instead of TAILQ as now it is a classic FIFO. - remove q_node pointer from ng_queue structure as it is not really needed. - reimplement item queue using STAILQ instead of own equal implementation. As soon as BT subsystem has own item queues using ng_item.el_next update it also. - change depth field in ng_item from uintptr_t to u_int. It was made uintptr_t to keep ABI compatibility.
