config RAW_DRIVER
tristate "RAW driver (/dev/raw/rawN) (OBSOLETE)"
help
The raw driver permits block devices to be bound to /dev/raw/rawN.
Once bound, I/O against /dev/raw/rawN uses efficient zero-copy I/O.
See the raw(8) manpage for more details.

The raw driver is deprecated and will be removed soon.
Applications should simply open the device (eg /dev/hda1)
with the O_DIRECT flag.

The maximum number of RAW devices that are supported.
Default is 256. Increase this number in case you need lots of
raw devices.
