@ -827,10 +827,6 @@ but in the event of any barrier requests in the tag queue we need to ensure
that requests are restarted in the order they were queue. This may happen
if the driver needs to use blk_queue_invalidate_tags().
Tagging also defines a new request flag, REQ_QUEUED. This is set whenever
a request is currently tagged. You should not use this flag directly,
blk_rq_tagged(rq) is the portable way to do so.

DEBUGGING HINTS
To enable debugging messages, edit st.c and #define DEBUG 1. As seen
above, debugging can be switched off with an ioctl if debugging is
compiled into the driver. The debugging output is not voluminous.
Debugging code is now compiled in by default but debugging is turned off
with the kernel module parameter debug_flag defaulting to 0. Debugging
can still be switched on and off with an ioctl. To enable debug at
module load time add debug_flag=1 to the module load options, the
debugging output is not voluminous.
If the tape seems to hang, I would be very interested to hear where
the driver is waiting. With the command 'ps -l' you can see the state
