dholland 05ce5c4223 Apply patch from PR 43587, mostly from martin and kre. When writing a
sysctl variable using ?= fails with EPERM, don't print an error
message.

Ideally setting a sysctl to the same value it already has should also
not fail regardless of permissions, but this would need to be done in
the kernel.
