Hi,

I'm trying to create a sysctl tree of the bufq strategies
available in the kernel to modify the hardcoded values
of its queues.

That's what I have:

[juan@Nocturno][~]> sysctl kern.bufq
kern.bufq.priocscan.burst.noncritical = 64
kern.bufq.priocscan.burst.limited = 16
kern.bufq.priocscan.burst.critical = 4
kern.bufq.readprio.read_burst = 48
kern.bufq.readprio.write_req = 16
kern.bufq.strategies = disksort fcfs priocscan readprio
[juan@Nocturno][~]>

The problem is the following:

[juan@Nocturno][~]> sudo sysctl -w kern.bufq.readprio.write_req=64
kern.bufq.readprio.write_req: 16 -> 64
[juan@Nocturno][~]> sysctl kern.bufq.readprio.write_req
kern.bufq.readprio.write_req = 16
[juan@Nocturno][~]>

Does anyone know what's the problem?

(Patch attached too).

Thanks...
