Created attachment 168943
  --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D168943&action=
=3Dedit
updated patch series, applies to -r297514

We were running into this same bug at iX, so I ported the original patch to=
 the
HEAD kernel (which required a bit of tweaking) and then added my own changes
(see commit text for descriptions).  Then I back-ported it back to the iX
kernel which is a bit behind HEAD (and fixed typos in both versions, etc),
where it is now at least lightly tested.

I'll attach the updated patches as a series of git commits suitable for "git
am" (on the github version of the FreeBSD tree); feel free to redo them in =
some
other form, including perhaps combining Yuri's original patch and the small
subsequent fixes.  The last (and large) "rewrite for clarity" section proba=
bly
should stay a separate patch though.
