From: Robert Love <rml@tech9.net> To: linux-kernel@vger.kernel.org Subject: Updated preempt-kernel patches Date: 12 Oct 2001 16:19:36 -0400 Updated preempt-kernel patches for 2.4.10, 2.4.12, 2.4.13-pre1, and (phew!) 2.4.12-ac1 are available at: http://tech9.net/rml/linux Note the patches for 2.4.10 are updated over previously releases. These patches allow create a preemptible kernel -- increasing system response time. Everyone is encouraged to give it a whirl and report back. Major changes include code to prevent CPU changes on preempt (should prevent a class of race conditions), an SMP compile fix, and various cleanups. Full change log: 20011011 - remove pgalloc.h preemption disable statements -- not needed with the new CPU switch prevention - fix compile on SMP in some configurations (ac tree only) 20011005 - rearrange sched.c so we can patch cleanly against rtsched (or vice versa) 20011004 - prevent the case of preemption causing a CPU switch by locking tasks to the current CPU in preempt_schedule - revert to _raw_spin_xxx from _spin_xxx since PPC uses that convention. 20011003 - push pcmcia-cs tools fix into their next release 20011001 - fix spin_lock_prefetch optimization causing (harmless) compile warnings Robert Love - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
