Hi -current,

I found a reproducible panic with GELI's 'detach on close' feature
interfering with 'zpool scrub' of an eli provider.

root@roadrunner: ~# zpool status
pool: tank
state: ONLINE
scrub: scrub completed with 0 errors on Thu Aug 30 19:35:14 2007
config:

NAME STATE READ WRITE CKSUM
tank ONLINE 0 0 0
ad0s4d.eli ONLINE 0 0 0

Where /usr and /var are on tank (among others). This setup is working
just fine (module buffer cache anomalies). Anyway, I issued a 'zpool
scrub tank' just for kicks, here's the panic (hand transcribed):

# zpool scrub tank
GEOM_ELI: Detached ad0s4d.eli on last close.
panic: function g_eli_orphan_spoil_assert() called for ad0s4d.eli
panic()
g_eli_orphan_spoil_assert()
g_spoil_event()
g_run_events()
g_event_procbody()

Yes, ZFS doesn't open providers and keep them open, it just opens them
as needed, so GELI detach-on-close feature is no good here.
