This series fixes the clone3 not implemented warnings I have been seeing
during recent builds. It was a simple case of implementing copy_thread_tls
and turning on clone3 generic support. Testing shows no issues.

Sure, I updated it in the 'docs' commit, but as you mention I can just remove the mention of clone* all together. I will just remove that here and it won't have to be touched in the 'docs' commit. ^ permalink raw reply [flat|nested] 12+ messages in thread

It might make sense to either skip the tests of have them as expected fails when CONFIG_NAMESPACES is off. On the otherhand, I am not sure if the self tests know about the CONFIG_* available. I notice many test directories have a 'config' file and a readme saying, for these test to run ensure use have at least 'these' config values set. -Stafford ^ permalink raw reply [flat|nested] 12+ messages in thread
