rwlock(9) upgrade
Hi, For rwlock(9), there is no rwlock_upgrade function. Is it safe to use rw_wlock() for that purpose? In other words, Does calling rw_wlock() upgradeanalready r-locked lock? -- Best regards.

No, calling rw_wlock when you hold the lock in read mode will deadlock. lockmgr(9) supports LK_UPGRADE, but note (see the recent commit for LK_TRYUPGRADE) that LK_UPGRADE, if it cannot do the upgrade immediately, e.g. due to multiple shared lockers, will unlock and wait to finish the upgrade. In general, the idea is that upgrade is not a good operation, since there's no way to know ahead of time if it can be done without a lock release. So code is better off explicitly unlocking the shared/read-mode lock and explicitly blocking for an exclusive/write lock.

cause of reboot
Hi, my server reboots every night and same o'clock last 10 days. But this machine's uptime was 96days. Suddenly reboot this machine and now this continue every night again and again. I didn't find any reason and I didn't change anything else. I looked last command, reboot ~ ~ AM 03.15 ~ I checked dmesg -a , it has only generic things no other things. I checked /var/log/messages I wrote script and checked swapinfo , cpu and memory but all of them was normal before reboot. I checked crontab and scripts. I checked crashinfo but no dump from kernel. I didn't find any useful info from this commands. I checked praudit /var/audir/20130930..CrashRecovery and I didn't understand very well from this file but I think this means my machine crash and reboot isn't it?? And How can I understand what is the reason of rebooting my FreeBSD8.3 server.

If not, then replace reboot (and friends) with a script that reports who called it. ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to freebsd-hackers-unsubscr...@freebsd.org

Re: best way to make dvd appear to me a .iso file to the FS
That solution works only for a FreeBSD install disk. I am looking for a more general solution, for an install CD/DVD for any x86-compatible OS. (Currently bhyve cannot handle other OS's besides FreeBSD, but they are planning to add support for other OS's.) (I am one of the developers of PetiteCloud, a forthcoming front end for bhyve. See the virtualization list for details.)
