Re: patch: atapi dvd-ram support

[Hisaaki Shibata <shibata@luky.org>]

Hello

I did patch 2.2.17 tree with dvd-ram-2217p17.diff.bz2.

At that time, following patch is rejected.
I think these lines should be removed from patchs.

	@@ -1329,7 +1369,7 @@
	 static
	  void cdrom_sleep (int time)
	   {
	   -       current->state = TASK_INTERRUPTIBLE;
	   +       __set_current_state(TASK_INTERRUPTIBLE);
	           schedule_timeout(time);
	    }

After removing these, I could make bzImage.

But I could not mkudf nor mkext2fs to my ATAPI 9.4GB new DVD-RAM drive.

How can I read/write DVD-RAM media like MO drive?

I can read/write ATAPI 5.2GB DVD-RAM media with 2.2.16 ide-scsi mode in ext2fs.

Best Regards,
