I re-ran the injection tests on my side (linux-next 20261019):
two runs with a 30ms kprobe
hold on every refresh of current_hweight() and one with the hold on every
50th refresh, same rt/s1..C topology and 1 <-> 10000 weight alternation
load as before. No WARN or oops, and the tracepoint hweight fields decoded
within [1, 65536] in every run.

For the series:
