Description

While review a build I noticed the following in config.log:

configure:9716: result: no
configure:9724: checking if kernel has sk_sleep

It seem there is a check for sk_sleep but later it cannont build with it.

I looked at the HUGE "configure" file but was scared away for now. Just filing an LU to track the build issue.
