Bug ID: 192926
Summary: [patch] sched_yield is a no-op
Product: Base System
Version: 10.0-RELEASE
Hardware: Any
OS: Any
Status: Needs Triage
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: freebsd-bugs@FreeBSD.org
Reporter: e...@vangyzen.net
Created attachment 146161

proposed patch
sched_yield() is a no-op. The thread is put back on the CPU immediately,
preventing other threads from running. ru_nvcsw gets incremented, but ktrace
does not show a context switch.
This was introduced by r239157:
http://svnweb.freebsd.org/base?view=revision&revision=r239157
I found this on 10.0-RELEASE-p7, but the same code exists in head.
I will attach a test case and patch against releng/10.0.
