Darik Horn 74497b7ab6 Add zvol_inhibit_dev module option. ... ZoL can create more zvols at runtime than can be configured during system start, which hangs the init stack at reboot. When a slow system has more than a few hundred zvols, udev will fork bomb during system start and spend too much time in device detection routines, so upstart kills it. The zfs_inhibit_dev option allows an affected system to be rescued by skipping /dev/zd* creation and thereby avoiding the udev overload. All zvols are made inaccessible if this option is set, but the `zfs destroy` and `zfs send` commands still work, and ZFS filesystems can be mounted.
