Since VOP_*() requires a filesystem (with "/" specifying "all of this
fs"), per-zvol or per-vdev "bleaching" needs a different implementation
vehicle, that's clear, as you don't have any handle then that you could
call it with.
I wouldn't just brush the VOP_*() approach aside. The world isn't pure
ZFS there's more to it, whether you wish otherwise or no ...
I agree, but I think these things are complementary and that isn't
solving the problem I was trying to solve since it requires someone make
explicit calls other than unlink(2) or similar.
