scheduler parameter inheritance on clone()

scheduler parameter inheritance on clone()

[Christopher Friesen]

The pthreads standard specifies that the default behaviour is that new 
threads should be created with the SCHED_OTHER policy and a priority of 0.

However, it appears that the kernel will create new tasks (be they 
threads or processes) with the same settings as the parent.

If CLONE_THREAD is set, should the kernel perhaps set the policy and 
priority as specified by pthreads?

Sorry, I've since found out that this was actually an issue with the man 
pages (same problem on two different distros).  The man pages were still 
from LinuxThreads, but the NPTL behaviour was different.

Apparently the spec doesn't actually specify the default behaviour, it's 
implementation dependent.

My mistake.
