PJD told me once that ZFS is always using UMA, it is just not using it for everything (except when the sysctl is switched to use it for everything). FYI: I have a 9-current system which panics (without a backtrace/dump) after 1-2 days of uptime when the zfs-uma-sysctl is activated. When it is not activated it survives several weeks (let's say about a month). So any work on the UMA fragmentation issue is well spend time. No, I haven't tested any of the patches on this machine.
