Why to add this functionality to the block layer instead of somewhere
in the drivers/ directory?
Simply because we need notifications about appearing and disappearing
block devices, or a way to iterate over all block devices in a system.
For both there isn't currently any other interface than using a
class_interface for that, and that requires access to &block_class
which is considered a block subsystem internal.
That's an argument for adding an interface to the block layer that
implements this functionality but not for adding this code in the block
layer.
Thanks,
Bart.
