 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.
