As noted already, your patch has been applied, and at least the
system no longer wedges as it did before.

The two-lwp deadlock I observed after booting the kernel with the
patch appears to be unrelated to the original issue I reported, and
appears to be a VFS cache issue, yet to be diagnosed.

I'm now running a "LOCKDEBUG.MP" kernel on this machine, and it has
now managed to complete a full "build.sh -x ... release" without
locking up, something which I could not do before, and the VFS issue
has not re-surfaced either.

I would therefore say that the patch should be committed if it has
not already, and also pulled up to netbsd-10.

Best regards,
