Modified files:
sys/kern vfs_bio.c kern_physio.c
sys/i386/i386 trap.c
Log:
Modify the scheduling policy to take into account disk I/O waits
as chargeable CPU usage. This should mitigate the problem of processes
doing disk I/O hogging the CPU. Various users have reported the
problem, and test code shows that the problem should now be gone.
