CVS commit: [yamt-idlelwp] src/sys

[Andrew Doran <ad%netbsd.org@localhost>]

Module Name:    src
Committed By:   ad
Date:           Wed Apr  4 22:28:18 UTC 2007

Modified Files:
        src/sys/kern [yamt-idlelwp]: kern_synch.c
        src/sys/sys [yamt-idlelwp]: cpu.h

Log Message:
Add cpu_did_resched() and call with the per-CPU scheduler lock held.
Needed to interlock with cpu_need_resched() on other CPUs, as there
is a short window where the flag could be clobbered while a higher
priority LWP is waiting to run.
