[PATCH 00/63] ide-cd: redux

[Bartlomiej Zolnierkiewicz]

Hi,

This patch series is a major rework of the ide-cd driver.

The motivations behind it are twofold:

* ide-cd is still in use but because it has been out of luck for maintainers
  lately the code become quite hard to debug and maintain - this puts it back
  into the shape

* aid efforts of developers (Tejun and Alan) who are working on libata ATAPI
  support - it should be now a lot easier to spot the various quirks for
  weird/buggy devices, differences between sr/ide-cd etc.

This patch series contains only safe/straightforward changes (some "risky"
ones are scheduled for later time) and should be fully bisectable.


Changes:

* unify _four_ slightly different IRQ handlers into one

* re-organize handling of quirky-devices (group quirks scattered
  all over the driver in the table and handle them using flags)

* move code for verbose error logging to ide-cd_verbose.c (this
  code doesn't have any IDE subsystem dependencies so if desired
  it can be easily converted into generic IDE/libata library)

* move code handling cdrom.c IOCTLs to ide-cd_ioctl.c

* remove duplicated/dead code (> 700 LOC gone)

* move historical changelog to Documentation/ide/

* fix few bugs discovered during rewrite

i'd like to take that position if nobody objects. I've done some work around the
kernel here and there and i think its time for me to get serious.

Thanks.

Hi, in the future could you please post big patchbombs like this as 
replies to the first one so they fold nicely into one thread?  IIRC, 
git-send-email does this by default now.

woo-hoo.

boo-hoo.

I wish someone would fix that "The drive appears confused (ireason =
0x%02x)" thing.  I had a go a while back but iirc the reporter disappeared
on me.  It is somewhat common.

Or do you think this patch might indeed fix it?

Andrew, take a look at patch #12 in this series: "ide-cd: fix "missing data" handling in
cdrom_pc_intr()."
