Subject: [Xenomai-core] [PATCH 2/6] POSIX: Fix initialization of SCHED_RR threads
Date: Mon, 15 Dec 2008 15:34:36 +0100	[thread overview]
Message-ID: <20081215143436.15493.20810.stgit@domain.hid> (raw)
In-Reply-To: <20081215143435.15493.94798.stgit@domain.hid>

Passing SCHED_RR as policy to pthread_create has currently not the
desired effect. The kernel part expects that user space adjusts the
policy and prio via __pse51_thread_setschedparam after setting up the
shadow. And this is what the patch does by calling the wrapped
pthread_setschedparam instead of the real one.
