Interestingly this looks like an upstream bug as well. If for some reason we are unable to get a zvols statistics, because perhaps the zpool is hopelessly corrupt, we would trigger the VERIFY. This commit adds the proper error handling just to propagate the error back to user space. Now the user space tools still must handle this properly but in the worst case the tool will crash or perhaps have some missing output. That's far far better than crashing the host.

Native ZFS for Linux! ZFS is an advanced file system and volume manager which was originally developed for Solaris. It has been successfully ported to FreeBSD and now there is a functional Linux ZFS kernel port too. The port currently includes a fully functional and stable SPA, DMU, and ZVOL with a ZFS Posix Layer (ZPL) on the way!
Documentation for building, configuring, and using ZFS can be found at: http://wiki.github.com/behlendorf/zfs/
