Ah, I had assumed that branch was destined for the next release. If it
is for 5.19 and they make -rc3 then it should be trivial for Paul to
either rebase the changes on -rc3 and apply that diff as part of
"context_tracking: Take IRQ eqs entrypoints over RCU" (if his tree is
mutable) or just merge -rc3 and apply that diff as part of the merge. I
don't really care how it gets resolved, just so long as it does :)
Cheers,
