CVS commit: src/sys

[David Laight <dsl%netbsd.org@localhost>]

Module Name:    src
Committed By:   dsl
Date:           Sat Jun 30 22:16:39 UTC 2007

Modified Files:
        src/sys/dev/isa: mcd.c
        src/sys/dev/scsipi: cd.c
        src/sys/sys: cdio.h

Log Message:
The cd ioctl definitions are not condusive to being called from within
  the kernel (eg from withthe linux compat code).
Add CDIOCREADSUBCHANNEL_BUF and CDIOREADTOCENTRIES_BUF which are like the
  existing ioctls withoutthe _BUF, except that the data area immediately
  follows the control structure (and is fixed length).
Modify scsipi/cd.c so that it only ever has one 'struct cd_formatted_toc'
  allocated on the stack (maybe this info ought to be in the softc)
  structure since even one 800 byte on-stack buffer isn't overly friendly.
cdplay(1) still seems able to read the track-list of an ATAPI cd.
