Arnd,
Thanks for following up! I was cleaning up some other part of the drivers (not
related to IDE/SCSI)
And on my todo list is to clean up the IDE/SCSI drivers. I will go through the
libata code and see
If there is anything in there that I can use to make these drivers somewhat
saner.
I am not sure if I can combine them into one yet, Hyper-V treats both drivers
differently. And there
Are some rumored changes to Hyper-V that would make these changes maybe even a
bit more difficult.
I will use this mailing list to bounce ideas off of.
I still need to clean up your other suggestion as well, the static declarations
:)
For a more general question, When/if we make it out of staging, where should
these drivers live?
drivers/hyper-v or drivers/scsi and drivers/ide.
Is there a standard that is being followed?
Hank.
