--- Comment #2 from Konstantin Belousov <kib@FreeBSD.org> ---
All "zfs" thjreads wait for some zfs vnode lock.  It is crucial to understand
which lock is it, and what does it owner do.

I do not see an obvious owner candidate from the backtraces, but there are a
lot,
so it is not hard to miss it.

Follow
https://docs.freebsd.org/en/books/developers-handbook/kerneldebug/#kerneldebug-deadlocks
to gather the required debugging info.
