This patch is far too big IMHO ;-)
It would be great if you can split this patch an create a patch series.

Instead of backporting patch 0003, try to rebase patch 0008 over busybox 1.31.1.

But for the remaining patches, maybe you can squash then since the patch 0007
remove the syscall wrappers around clock_gettime that was modified by patch
0004, 0005, 0006.

It would be great to ask upstream for a new release 1.32 or backport those
patches to 1.31.x.

Another solution would be using the current busybox master as a last resort.

Best regards,
Romain
