[patch 3/3] rtmutex: Modify rtmutex-tester to test the setschedulerpropagation

From: Thomas Gleixner
Date: Thu Jun 22 2006 - 05:09:18 EST

Next message: Thomas Gleixner: "[patch 1/3] Drop tasklist lock in do_sched_setscheduler"
Previous message: Thomas Gleixner: "[patch 0/3] rtmutex: Propagate priority setting into lock chains"
In reply to: Thomas Gleixner: "Re: [patch 2/3] rtmutex: Propagate priority settings into PI lockchains"
Next in thread: Thomas Gleixner: "[patch 1/3] Drop tasklist lock in do_sched_setscheduler"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

Make test suite setscheduler calls asynchronously. Remove the waits in the test
cases and add a new testcase to verify the correctness of the setscheduler
priority propagation.
