(I wouldn't file this if there were any kernel changes in this PR, but since it's all lzc_send...)

Describe the problem you're observing

While running ZTS, "fun" ensued with no warning I saw. No errors or panics found after a scrub on the zroot pool after rebooting.

Describe how to reproduce the problem

Unknown? Maybe run ZTS? A ZTS run immediately prior tried and succeeded in zfs unmounting /tmp while things were actively doing IO to it, no idea if related.

Include any warning/errors/backtraces from the system logs

(As you can tell, I have a vmcore to poke around in, if it would be helpful.) Last few lines in the ZTS log from the run where it died:

This appears to have been caused by zap_lookup() in vdev_obsolete_sm_object() failing because of a checksum error. In fact, it appears most of the vdev_obsolete_sm_object() callers don't have any error handling for this unlikely case. Reopening.
