BTW, I saw you've committed this. Thanks for that, and sorry for not
replying. I wanted to, but I've had a couple of day full of Internet
connectivity issues.
I do think it's best to keep the casts, although strictly unnecessary.
About this series, I'm re-sending patch 1, by replying directly to that
same email of this thread.
So, for other maintainers (which I'm Cc-ing to this message), or
should I say, for George :-), this is what should be considered for
review:
- [PATCH 1/3 v2] xenalyze: handle DOM0 operations events
- [PATCH 3/3] xenalyze: handle RTDS scheduler events
Thanks and Regards,
Dario
