Nah, but I'd like you, pls, to rewrite the commit message and explain more
prominently
1. resctrl does not support values than u32 max_bw
2. what this is really fixing and where the potential issue can come from and
what the situation is today.
I'd like to have more background in the commit message why we even arrived at
this patch.
I wouldnt've even done it - we have bigger fish to fry - but if you think it
is important for resctrl, sure.
Thx.
