+         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.
+
+         To compile this driver as a module, choose M here: the
+         module will be called pktcdvd.

+         This controls the maximum number of active concurrent packets. More
+         concurrent packets can increase write performance, but also require
+         more memory. Each concurrent packet will require approximately 64Kb
+         of non-swappable kernel memory, memory which will be allocated when

+         this option is dangerous unless the CD-RW media is known good, as we
