    [PATCH] preparation to use of driverfs refcounts, part 1 - partitions · afae25b7
    Alexander Viro authored
    	* update_partition() split into add_partition() and delete_partition().
    	* all updating of ->part[] is switched to these two (including initial
    filling/final cleaning).
    	* per-partition devices are allocated on-demand and never reused.
    We allocate struct device in add_partition() and put reference to it into
    hd_struct.  ->release() for that struct device frees it.  delete_partition()
    removes reference from hd_struct and does put_device() on it.  Basically,
    we get rid of problems with reused struct device by never reusing them...
    	At that point devices for partitions are nice and sane.
