Looks like these got marked as Rejected in patchwork.
I think either because lore is confused and attaches an exchange with
DaveM from 2022 to them (?) or because I mentioned to DaveM that I'm
not sure these are fixes. So let me ask - on a scale of 1 to 10, how
convinced are you that these should go to Linus this week rather than
being categorized as general improvements and go during the merge
window (without the Fixes tags)?
