Modified Files: src/sys/dev/raidframe: rf_driver.c rf_engine.c rf_netbsdkintf.c rf_paritymap.c rf_raid.h rf_states.c Log Message: convert the iodone_lock to a mutex, and use a condvar for signalling. this only handles the smallest use of old simple_lock/tsleep/wakeup APIs inside raidframe, and it points out that cv(9)'s have only one wait channel per cv, whereas each tsleep() caller can specify a different wait channel. this change removes the difference between normal raidio and waiting for IO during shutdown. i've tested this one 3 systems, ran atf, and had mlelstv and rmind review the change.
