Subject[PATCH 00/40] ide: generic ATAPI support


This patch series unifies ATAPI support present in ide-{floppy,tape,scsi}
device drivers and moves it out to the core IDE code (new ide-atapi.c file).

In the process many bugs were shaken out and ~300 LOC were removed.


drivers/ide/Kconfig | 6
drivers/ide/Makefile | 1
drivers/ide/ide-atapi.c | 296 ++++++++++++++++++++++
drivers/ide/ide-cd.c | 5
drivers/ide/ide-floppy.c | 431 +++++++-------------------------
drivers/ide/ide-tape.c | 630 ++++++++++++++---------------------------------
drivers/scsi/ide-scsi.c | 455 +++++++++++----------------------
include/linux/ide.h | 28 +-
8 files changed, 777 insertions(+), 1075 deletions(-)

Now, while this is a big step in the right direction there are still some
things left on TODO for generic ATAPI support to be complete:

- convert ide-cd to use generic ATAPI code

- kill pc and rq stacks in ide-{floppy,tape}

- generic handling of REQUEST SENSE command

- generic handling of MODE SENSE command for ide-{floppy,tape}

- convert ide-{cd,floppy,tape} to use scatterlists for PIO transers
(ala ide-scsi)

I know that Borislav is working on the first two items but other ones
are free at the moment so if you feel brave you may give it a try :-).

PS I'll be travelling during this weekend and be rather busy with day job
so replies from me may be delayed a bit.
