| H A D | if_tap.c | diff 240938 Tue Sep 25 20:20:01 MDT 2012 emaste Avoid INVARIANTS panic destroying an in-use tap(4) The requirement (implied by the KASSERT in tap_destroy) that the tap is closed isn't valid; destroy_dev will block in devdrn while other threads are in d_* functions. Note: if_tun had the same issue, addressed in SVN revisions r186391, r186483 and r186497. The use of the condvar there appears to be redundant with the functionality provided by destroy_dev.
