Bug with sched_lend_prio?
I have enabled PREEMPTION, FULL_PREEMPTION with ULE. Now I get strange result here:
- propagate_priority gets a TD_ON_LOCK(td)
- It tries to panic(), unfortunatelly, ts->ts_lockobj here is NULL
- A fatal trap 12 happens.
It seems that ts->ts_lockobj was touched by sched_lend_prio, for unknown reasons. Maybe there is some lock releases?

调试能力明显下降了，本来早就应该想到的，结果整整花了一个钟头才找到故障点，老了，明明看到堆栈毁了的居然还去相信调试器：（

参与评论How to represent some type inherted from other template, in a C++ template class?
It’s not quite easy to represent a type that is found in base “template class”. Consider the following code:
template <class Key,class T> class CMyClass: public map<Key,T> { public: void lookup(Key x) { map<Key,T>::iterator iter; iter = find(x); } };

参与评论Proposed new RELENG_5_3 errata candidate
The following change is considered as a new errata candadite from my view:
peter 2005-04-18 21:36:17 UTC FreeBSD src repository
Modified files: (Branch: RELENG_5_4)
sys/i386/i386 genassym.c vm86bios.s
sys/i386/include pcb.h
Log:
MFC: stop i386_vm86() from either panicing or trashing random pages.
This can improve stability, however we can not easily prove that it is producable :-) So I have turned that to re@.
参与评论流水账
最近几天网上不怎么太平。
白天办了保险的最后一道手续，当然希望还是不要用的好，但至少哪天自己有什么事情的话，以后还能有人能照顾爹妈养老……：（
下午终于完成了一个想了很久但没做的技术上的事情，一直折腾到晚上9点多，回家。
给一个孩子捐了点钱，不算多。不过发现学校的所谓主流媒体对号召捐款的事情只字没提，汗……这事儿要不是听liukang说我一点都不知道呢。
开始听一个研究生说这事儿公费医疗能报，所以不捐，觉得那个人很冷漠；后来听一个大学同学分析说那个人家里超生，而且这个病没什么办法治疗，我骂了一句，靠，到时候你得了病也别找我们。
