The annotated tag zfs-0.5.2 has been created by allanjude: URL: https://cgit.FreeBSD.org/src/tag/?h=zfs-0.5.2 tag zfs-0.5.2 Tagger: Brian Behlendorf <behlendorf1@llnl.gov> TaggerDate: 2010-11-12 21:57:17 +0000 ZFS Version 0.5.2 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iEYEABECAAYFAkzduD0ACgkQCrnpkcavZYsC4QCfQkan1399tvn6qqRtJ9q9RTSp 63IAoNleFR15qrTtMLxWWu3UQnHdXQS9 =U6HP -----END PGP SIGNATURE----- commit 5e7affae52365f9f329cc63a53ae570352c4d993 Author: Brian Behlendorf <behlendorf1@llnl.gov> AuthorDate: 2010-11-12 17:33:17 +0000 Commit: Brian Behlendorf <behlendorf1@llnl.gov> CommitDate: 2010-11-12 17:33:17 +0000 Skip /dev/hpet during 'zpool import' If libblkid does not contain ZFS support, then 'zpool import' will scan all block devices in /dev/ to determine which ones are components of a ZFS filesystem. It does this by opening all the devices and stat'ing them to determine which ones are block devices. If the device turns out not to be a block device it is skipped. Usually, this whole process is pretty harmless (although slow). But there are certain devices in /dev/ which must be handled in a very specific way or your system may crash. For example, if /dev/watchdog is simply opened the watchdog timer will be started and your system will panic when the timer expires. It turns out the /dev/hpet causes similiar problems although only when accessed under a virtual machine. For some reason accessing /dev/hpet causes qemu to crash. To address this issue this commit adds /dev/hpet to the device blacklist, it will be skipped solely based on its name.
