Hi all
I've tried to check related scheduler code and I've got impression
that in CFS scheduler, dynamic priority level no longer determines
which process will be picked up by the scheduler. Instead, it is now
the waiting time that becomes the primary factor to watch...the longer
it waits, thus it is treated "more unfair"...then it will be picked
ASAP. Is this correct?
AFAIK, this is correct
If it is correct, then is it still useful to assign different nice
level to mark the importance of a process?
Waiting time for different process are virtual time, I mean waiting time depends on priority of the process also.
Waiting time of a process with higher priority will increase faster so that it get picked sooner.

Thanks in advance for your help.
