Real Time scheduler infos

[Ivan Gualandri]

Hi, 

i have a question about priorities in RT patchset. 

In linux priorites are from 1 to 139 (1 highest - 139 lowest)
And RT prorities are between 1 to 99. An i think 1 is highest and 139
lowest.

But now if i try to launch three tasks with 3 different priorities: 
for example 
A has priority 10
B has priority 20
C has priority 30 
I notice that the tasks B and C are always the first two to run. And A
always wait the end of B or C (also if A is the first task launched).

Now my question is: 
when i set priority of a RT task (changing the sched_priority field of my
task) the highest priority is 99 or 1? 

Thanks,
--i

P.s. Sorry for my bad english!
