jhb 2004-08-04 20:24:40 UTC FreeBSD src repository Modified files: sys/kern kern_synch.c Log: Workaround a possible deadlock on SMP due to a spin lock LOR by disabling the immediate awakening of proc0 (scheduler kproc, controls swapping processes in and out). The scheduler process periodically awakens already, so this will not result in processes not being swapped in, there will just be more latency in between a thread being made runnable and the scheduler waking up to swap the affected process back in. Revision Changes Path 1.256 +6 -0 src/sys/kern/kern_synch.c
