Alan Somers d4b9233a96 Add a sysctl to allow ZFS pools backed by zvols ... Change 294329 removed the ability to build ZFS pools that are backed by zvols, because having that ability (even if it's not used) leads to deadlocks. By popular demand, I'm adding an off-by-default sysctl to reenable that ability.
