Thanks, Ingo. I understand. However the "history" of this patch is not as
simple as u represent. ;)
It was originally written by Ido and I just posted it (then I put my SOB at
the end of SOB list). But after u noted that it didn't compile on !SMP i
reworked it but yet Ido did at least half of the coding, so I put my SOB at
the first place (as I was the last one writing the code) and then Ido's as he
actually wrote the code in this patch as well and I do wanted to give him a
credit.
Do u still think changing his (Ido's) SOB to Acked-by was the right thing to
do?
Thanks,
vlad
