Hmmm, It appears that now we need a gendisk per disk, rather than per controller, as this snippet from patch-2.5.30 implies? And we need to set the gendisk's first_minor to be the minor number of the first partition for each disk, is that about right?
- hd_gendisk.nr_real = NR_HD; - - for(drive=0; drive < NR_HD; drive++) - register_disk(&hd_gendisk, mk_kdev(MAJOR_NR,drive<<6), 1<<6, + for(drive=0; drive < NR_HD; drive++) { + hd_gendisk[i].nr_real = 1; + add_gendisk(hd_gendisk + drive); + register_disk(hd_gendisk + drive, + mk_kdev(MAJOR_NR,drive<<6), 1<<6, &hd_fops, hd_info[drive].head * hd_info[drive].sect * hd_info[drive].cyl)
I think this is why cciss is broken, we have just one gendisk per controller. (please pardon my ignorance, I haven't ever had to look at this partition related code before.)
