What archs (in Buildroot context) are affected by this?

Hi Peter,

All of the existing architectures in buildroot support the sysctl
syscall. However, this patch will not cause any problem
for these architectures anyway.

This patch was never applied to Buildroot, but libevent has been
updated to 2.0.21 recently, and my understanding is that the sysctl
problem is fixed in 2.0.21.

Therefore, I'm marking this patch as "non-applicable" in patchwork.
Do not hesitate to resend an updated patch if my understanding turns
out to be wrong.

Thanks!

Thomas
