well, it might not be strictly related to the rest of the commit, right.

i think VOP_INACTIVE should be called here,
at least when LK_SLEEPFAIL is involved.  (checkalias)
(i don't think using LK_SLEEPFAIL is a good idea,
but it's a separate topic.)

do you mean eg. introducing another flag to make vclean exclusive?

i agree it would be nicer.  however, as i have a plan to create
a branch to separate vgone from vnode lock, and it can change this code,
i don't want to work so hard to make this nicer at this point.
