sysfs interface

The pktcdvd module (packet writing driver) creates the following files in the
sysfs: (<devid> is in the format major:minor)

What: /sys/class/pktcdvd/device_map
Date: Oct. 2006
KernelVersion: 2.6.20
Contact: Thomas Maier <balagi@justmail.de>
Description:
========== ==============================================
add (WO) Write a block device id (major:minor) to
create a new pktcdvd device and map it to the
block device.
remove (WO) Write the pktcdvd device id (major:minor)
to remove the pktcdvd device.
device_map (RO) Shows the device mapping in format:
pktcdvd[0-7] <pktdevid> <blkdevid>

Date: Oct. 2006

Contact: Thomas Maier <balagi@justmail.de>

Contact: Thomas Maier <balagi@justmail.de>
Description:
packets_started: (RO) Number of started packets.
packets_finished: (RO) Number of finished packets.
kb_written: (RO) kBytes written.
kb_read: (RO) kBytes read.
kb_read_gather: (RO) kBytes read to fill write packets.
reset: (WO) Write any value to it to reset
pktcdvd device statistic values, like
bytes read/written.

Date: Oct. 2006
KernelVersion: 2.6.20
Contact: Thomas Maier <balagi@justmail.de>
Description:
============== ================================================
size (RO) Contains the size of the bio write queue.
congestion_off (RW) If bio write queue size is below this mark,
accept new bio requests from the block layer.
congestion_on (RW) If bio write queue size is higher as this
mark, do no longer accept bio write requests
from the block layer and wait till the pktcdvd
device has processed enough bio's so that bio
write queue size is below congestion off mark.
A value of <= 0 disables congestion control.
============== ================================================
Example:
--------
To use the pktcdvd sysfs interface directly, you can do::
# create a new pktcdvd device mapped to /dev/hdc
echo "22:0" >/sys/class/pktcdvd/add
cat /sys/class/pktcdvd/device_map
# assuming device pktcdvd0 was created, look at stat's
cat /sys/class/pktcdvd/pktcdvd0/stat/kb_written
# print the device id of the mapped block device
fgrep pktcdvd0 /sys/class/pktcdvd/device_map
# remove device, using pktcdvd0 device id 253:0
echo "253:0" >/sys/class/pktcdvd/remove

Note: This driver is deprecated and will be removed from the
kernel in the near future!
If you have a CDROM/DVD drive that supports packet writing, say
Y to include support. It should work with any MMC/Mt Fuji
compliant ATAPI or SCSI drive, which is just about any newer
DVD/CD writer.
Currently only writing to CD-RW, DVD-RW, DVD+RW and DVDRAM discs
is possible.
DVD-RW disks must be in restricted overwrite mode.
See the file <file:Documentation/cdrom/packet-writing.rst>
for further information on the use of this driver.

module will be called pktcdvd.
