There was a problem hiding this comment.
Seems like a reasonable cause and fix!
Thanks for your work on this issue, it was a pain when doing testing on zstd last few weeks!
I can confirm your testing is valid @behlendorf
While doing many runs of zstd for zstd last few weeks, it hits about 0.6 times in every push on buildbot.
A few hours of zloop on a faster machine would've atleast had one of these.
LGTM.

Motivation and Context
Resolve #8602 which is one of the more common ztest failures
encountered by the CI.
Description
Any running
zpool initializeor TRIM must be cancelled priorto the
vdev_metaslab_fini()call in spa_vdev_remove_log() whichwill unload the metaslabs and set ms->ms_group == NULL.
How Has This Been Tested?
Unfortunately, I've been unable to consistently reproduce this
issue locally. I've run
ztestwith this PR applied for severalhours and was unable to reproduce the issue. However, since the
CI does relatively frequently hit this issue I've opened this PR for
additional testing and increased the ztest run time to 2 hours.
