Subject: Build failure for perf daemon on perf-tools-next
Hi,
I hadn't notice this before, its like this code isn't being
built and some change made it build or that daemon->start field (or curr
local variable) changed its type or we have a new compiler that has a
new type check, I'm still checking:
