[PATCH] Documentation for IDE and CDROM ioctls
I've written two document files, and packaged them as a patch. Two things caught my eye while I was writing this up: The header comments for CDROMREADRAW, CDROMREADMODE1, and CDROMREADMODE2 disagree with the actual source code. The header comments imply that a cdrom_read structure is used to pass data, but the source code actually reads a cdrom_msf structure and then overwrites it with raw data. I'm not sure if there's a bug in the header comments, in the driver source, or I misread something. The CDROM_LOCKDOOR ioctl seems to lock/unlock all doors on all drives, because it uses a global variable.
