Hi,

In the attached test program I test the scheduler lock operation with
pthread_set_mode_np and the PTHREAD_LOCK_SCHED bit mask.

Description:
Two tasks are created.
t1 lock the scheduler then load the cpu, sleep then load the cpu again but
t2 task start when t1 sleep while the scheduler is locked. Why t1 is
preempted?

I run on Xenomai 2.6.2 with linux kernel 3.2.21.

Thanks in advance.

Alex
