Thanks, I didn't notice that. It should be too risky to pull these up
just before RC1.
I withdraw this proposal.

PS
It would be really nice if we can find some systematical/reliable methods to
figure out files that really depends on struct syncobj, e.g.. I tried
ctfdump(1) to
*.o for kernel modules, but I cannot extract information better than
``grep syncobj.h .depend''...

Thanks,
