By now mutexes are used by io subsystem: All input/output requests (iors) and queues of iors are guarded by spin mutexes. As for devices, their NewBus sided structures will be guarded by (spin?) mutexes. > Does it support non-giant enabled input drivers? I don't really get what you mean. Did that answer about NewBus sided structures + paralleled/serialized ior processing clarify anything? -- - Maxim Zhuravlev
