This change is correct, but I think the commit message is a little
unclear. What you're really trying to avoid is using the kernel stack
for waitset (because the kernel stack might get swapped out). The
unclear-ness comes from the fact that other memory allocators also give
wired kernel memory, not just malloc().
Could you maybe clarify that in the log?
