Hi John,
We could test this patch and it works fine. Regarding the usage of request->tag, We have some challenges there.
Pm80xx driver need tag for internal command as well. Tag is controller wide and we need to assign unique tag
for internal command as well. If we use request->tag, how can we get tag for internal commands ? If driver
allocate that, how can we make sure it will not conflict with the request->tag ?
I have posted a patchset for internal tags some time ago; at the time it
was blocked by the missing shared tagset functionality.
But seeing that we're having it now I guess I'll need to repost; that
addresses precisely the issue you've described.
Cheers,
Hannes
