Hi Jim, Thanks for the patch.
FYI, I applied it pristine, I have just renamed the function "get_non_system_block_devices()" instead of just "get_block_devices", so it is easier to understand what the function does without looking into it.
I'm very happy that you're proposing this type of refactoring, and I have to admit that the code is too much spagetti-like as it evolved over time... :/ So really, thanks a lot.
Note that if you want to retain your patch ownership, you could send merge requests, otherwise, I'm marked as the author of the patches, which isn't very nice to your good work. :)
Cheers, Thomas Goirand (zigo)
