Hi,

I have a SMP linux running on 85xx poweprc. Say on Core 0 and Core 1
two different processes are running and on both the schedular runs.
Now for some special case, if one of my process issues a ioctl which
gets serviced by a kernel module, I wish to slow the schedular on that
core only. Otherwise the performance will get degraded.

Should I use highest priority tasklet, will it be sufficient or i need
to do something special

-TZ

Not clear what you mean by "slowing the scheduler" or "performance will 
get degraded". The scheduler is not a process, it runs when something 
triggers it to run.
