Could the remaining hackbench.c warnings be fixed, or could the subject and
body clarify that this patch only addresses checkpatch style findings?

The configured targeted `make check` still reports a signed/unsigned
comparison in sender(), an implicit fallthrough in create_worker(), and an
uninitialized byte passed to write() in ready().

Verdict - Needs revision
