Yes, I have added the simpler fix from the private ZoL branch to my custom
kernel and will start deploying that. It applied cleanly to 12.0-RELEASE. I am
torn if it's worthwhile to continue testing with INVARIANTS enabled to see if
it still panics, or without and see if it still hangs. I am still not able to
replicate either case short of just waiting around for a system to do it - no
amount of fs IO or CPU stressing seems to do anything, although I have not
tried dbench like in the ZoL bug report. Fortunately I have access to quite a
few production systems...

I am attaching the patch in case anyone else wants to try it.

I imagine there will need to be a larger effort from someone (mmacy?) to
correctly bring in the fixes to the recent "large_dnode pool feature" from ZoL?
