Hi all,

/proc/scsi/scsi currently has a very dumb implementation of the seq_file
api which causes 'cat /proc/scsi/scsi' to return with -ENOMEM when a
large amount of devices are connected.

This patch impelements the proper seq_file interface which prints out
all devices sequentially.
The use of 'get_device()/put_device()' is interesting, as it relies on
->show being called after a successful call to ->start / ->next.
But the current seq_file implementation does it that way; and using
->stop doesn't quite work as it's end up being called several times for
no appearent reason.

But I'm all ears for a better solution.

Cheers,

Hannes
