You know what? That is exactly what I think, too. ;-)

I just did a quick hack locally to test the build time of cpio, and did
not try to think further, so I stupidly copied the target variant as-is
without thinking too much.

Then I saw it worked, got the required timings from a batch of 5 runs,
finished my reply to Atharva's fs/cpio patch, and decided to send this
patch too, without realising that it needed a bit more love.

Atharva, when you respin your fs/cpio patch, can you grab this one in
your tree and fix it as Arnout pointed out?

Regards,
Yann E. MORIN.
