>This ioctl() yields the access count maintained by the mid level
|
|
for this SCSI device. This number is incremented by each open()
|
|
call done by the upper level SCSI drivers (i.e. sd, sr, st and sg)
|
|
and decremented by those drivers' release(). [A driver's release()
|
|
corresponds to the last close() on a file descriptor, or is
|
|
supplied by the kernel when a process is aborted.] Each SCSI
|
|
device has a separate access count.</P
