    [PATCH] split "gendisk" to be per-disk, part 2 · 3f41fa2f
    Alexander Viro authored
    we are starting to split gendisks - now we can do that.  Done for
    ide, sd, pd, hd and mfm
    
    It's in transit - what we are aiming at is getting ->nr_real to 1 for
    all gendisks.  Once that will be done we will be able to simplify a lot
    stuff and remove ad-hackery.  First thing that will happen after that
    is death of ->nr_real, obviouslye.  Then we
    	(a) will merge ->major and ->first_minor into ->dev
    	(b) strip one level of indirection from  ->driverfs_dev_arr, ->de_arr
    and ->flags - they turn into single-element arrays and we will simply pull
    the (only) element into struct gendisk.  Kills a lot of ad-hackery in splitup
    code (fewer things to allocate).
    	(c) replace ->major_name with ->disk_name; kills most of the crap in
    disk_name(9) - it only has to care about adding partition number to the name.
