Hi,
I suggest that this special case be made into a new function, named
callout_drain_async() inspired from projects/hps_head and that r287196
be backed out, so that callout_stop() works like before. See:
https://reviews.freebsd.org/D3521
And that the following patch be MFC'ed to -current from
projects/hps_head after D3521.
https://svnweb.freebsd.org/changeset/base/287261
It should close the race in question.
