-/****************************************************************************
- *
- * rf_diskqueue.c -- higher-level disk queue code
- *
- * the routines here are a generic wrapper around the actual queueing
- * routines.  The code here implements thread scheduling, synchronization,
- * and locking ops (see below) on top of the lower-level queueing code.
- *
- * to support atomic RMW, we implement "locking operations".  When a
- * locking op is dispatched to the lower levels of the driver, the
- * queue is locked, and no further I/Os are dispatched until the queue
- * receives & completes a corresponding "unlocking operation".  This
- * code relies on the higher layers to guarantee that a locking op
- * will always be eventually followed by an unlocking op.  The model
- * is that the higher layers are structured so locking and unlocking
- * ops occur in pairs, i.e.  an unlocking op cannot be generated until
- * after a locking op reports completion.  There is no good way to
- * check to see that an unlocking op "corresponds" to the op that
- * currently has the queue locked, so we make no such attempt.  Since
- * by definition there can be only one locking op outstanding on a
- * disk, this should not be a problem.
- *
- * In the kernel, we allow multiple I/Os to be concurrently dispatched
- * to the disk driver.  In order to support locking ops in this
- * environment, when we decide to do a locking op, we stop dispatching
- * new I/Os and wait until all dispatched I/Os have completed before
- * dispatching the locking op.
- *
- * Unfortunately, the code is different in the 3 different operating
- * states (user level, kernel, simulator).  In the kernel, I/O is
- * non-blocking, and we have no disk threads to dispatch for us.
- * Therefore, we have to dispatch new I/Os to the scsi driver at the
- * time of enqueue, and also at the time of completion.  At user
- * level, I/O is blocking, and so only the disk threads may dispatch
- * I/Os.  Thus at user level, all we can do at enqueue time is enqueue
- * and wake up the disk thread to do the dispatch.
